https://community.wolfram.com RSS Feed for Wolfram Community showing any discussions tagged with Mathematica sorted by most replies. https://community.wolfram.com/groups/-/m/t/181759 I was wondering, it would be interesting to try to use the community as a way to request new functions that could be incorporated into new versions of Wolfram Language, in a colaborative way. Sometimes users simply don't have the whole/deeper system view, to understand that the requested function is or too specific, too broad or already implemented, but I believe that another times we can have a nice insights, that Wolfram Research people haven't yet, or that do not have received much attention  yet.  To the idea is: [b]Post your's requested Function as a answer to this question, and let's upvotes show the more interesting ones![/b] Some rules 1- One Post per function (or class of function), you can have more than one request. 2- Exemplify your function use.

In Version 10 on my HP Pavilion HPE Series it takes a little over a minute. Is this common experience? Is there some way to decrease this time? Does it have any thing to do with virus checking?

Meaning, what is its purpose? But for those of you pragmatists tempted to roll your eyes and just get on with using it, let me motivate the question with a chart: ![enter image description here][1] You don't need a model to figure out the long term trend in that time series. And someone, somewhere, in WR needs to be asking the question I am posing in this post, if they are seriously hoping to check that trend and reverse it. Now, let's be fair here. Firstly this is not just a Mathematica issue. For example, here's the comparable chart for Matlab: ![enter image description here][2] So I am not "picking on" Mathematica. Its a general problem for mathematical programming languages. Or perhaps I should say, more accurately, its a challenge for proprietary mathematical programming languages: ![enter image description here][3] Now this "analysis" is of course over-simplistic. It could be, for example, that the downward trend in Mathematica interest is a reflection of a decision by WR to increase prices over time, to maximize profits, i.e. it could conceivably be a *good* thing. But I rather suspect otherwise and instead tend to believe that Mathematica is losing influence and relevance, regardless of whatever I may think of the product. Another response might be: "Of course we are losing market share to license-free, direct competitor products. What's your point?". To which, I suppose, the answer might be: "Are you quite sure that is inevitable? Are there not examples of for-profit products that are so good they are able to maintain market share in the face of cost-free alternatives?". The answer to that question is, of course, yes. But in order to maintain your competitive position you have to be crystal clear in your understanding of what the value proposition is, and why customers will (continue to) pay for your product. Which brings me to the subject of this post: what is Mathematica for? Because unless can answer that question, you can't answer the earlier one. Now I have a theory that the generally held view in WR is that Mathematica is for any kind of programming task you can conceive of. It's a general purpose tool, limited in its capabilities only by your imagination. And at this point we could now queue up a 15 minute informercial featuring examples of applications from Astronomy to Zoology. But just because you *can* do something in Mathematica doesn't mean you should: there are often better alternatives. Mathematica has developed into something like a Swiss Army knife, a general purpose tool you can use for almost any purpose. But, often times what you need is a tool with a specific purpose, like a screwdriver, which will make it much easier to complete the task you have in mind. Let's take a simple example: spreadsheets. I have seen several attempts to get Mathematica to do the kind of thing that Excel can do effortlessly. And the question I always end up asking myself is: "why on God's green earth would anyone in their right mind try to use Mathematica for a task like that?". What is trivial to accomplish in a few seconds or minutes in Excel, typically takes hours of jumping through hoops with Mathematica to achieve a result that is almost always inferior. It's like trying to navigate a freeway in a spaceship, rather than a motor car. Sure, you can do it, buy why?? Another no-no is trying to develop stand-alone software applications in Mathematica. It's extremely hard to do - typically much tougher then using a language designed for that purpose. On the other hand, there are some things that Mathematica excels at, such as: - Mathematics/symbolic logic/symbolic manipulation: superb. Best of breed. - Graphics (including animation) ditto - Documentation. Also superb. Now as good at Matlab, possibly even superior. After that, you could pick a bunch of different application areas in which Mathematica is great. But best of breed? I dont know. Let's take an area I know a little about: time series analysis. prior to 2010, Mathematica was truly awful at handling time series. Basically it didn't. Gradually, over subsequent releases, Mathematica has made enormous strides in this area to the point where it is truly magnificent. For which someone at WL deserves (and I hope has received), several promotions. But despite this, Mathematica is still not best of breed in this area. Why? Because, unaccountably, it is still missing several vital elements of functionality such as Granger causality/ Cointegration and its implementation of important functionality like the Kalman Filter is horribly unintuitive. This shows two things: (i) it is possible for WR to make Mathematica outstanding in almost any area it chooses to. it's just a question of focus. And (ii) to become best of breed, you need to finish the job! By which I mean, provide something close to 99% of the functionality that a professional practitioner in that area would expect to have available. if it chose to, WR could accomplish that in the time series area in a single release, I would guess. The problem, I am suggesting, is that in trying to make Mathematica a product that is "all things to all men", it fails to achieve the status of being indispensable to practitioners in a more limited subset of subject areas. Ok let's go with this conjecture for a moment. Let's wave a magic wand and imagine that we can change Stephen Wolfram's vision about his flagship product, which he has sweated blood over for the last 20-30 years (in other words, this is never going to happen - but its still fun to play the game). What core capabilities would you have WR focus on with the aim of making Mathematica an indispensable product in that area? Here are my choices: (i) Time series & econometrics. Mathematica is so close: just finish the job - it's a no-brainer! (ii) Machine learning. This also means making sure that the GPU capability works as it should, first time and every time. Mathematica still has a way to go here and its a huge area. But I'm sure WR could do it. (iii). Meta-Programming. This one is a BIG stretch. But it just happens that WL may have a huge potential competitive advantage, because the language is itself *computational*. in other words, the building blocks of the language can themselves be manipulated, which is exactly what you need for meta-programming. Try doing that in Python! On this subject I would say that the starting point would be to create WL functionality capable of generating a single line of WL code that is sufficiently complex and interesting to win the Wolfram One-Liner competition. I realize that's a huge challenge and its not just about the difficulty of navigating the terrain of the Wolfram language. It also involves thinking about what "complex" and "interesting" mean, in this context. Think of this as a Turing test, for Metaprogramming capability. Once it's passed, it would open up a floodgate of possibilities, both for WL aficionados but also, critically, for those who don't program in WL, or indeed in any language at all.

Several sessions will be led by the Wolfram developers who work on the mathematics functionality that we'll be covering! While this study group is aimed at mathematics students at roughly the graduate level, **no prior Wolfram Language experience is necessary**—the first day will be dedicated to getting you up to speed with the language itself. As usual, we will have questions, study materials, quizzes along the way to help you master the subject matter and functionality. ![enter image description here][2] [1]: https://www.bigmarker.com/series/daily-study-group-math-research-wsg40/series_details?utm_bmcr_source=community "REGISTER HERE" [2]: https://community.wolfram.com//c/portal/getImageAttachment?filename=WolframUBanner%281%29%281%29.jpg&userId=1711324 Arben Kalziqi 2023-05-03T23:07:29Z https://community.wolfram.com/groups/-/m/t/288532 I am doing some project planning that could use the CDF Player and CDF technology as a means of distributing a mathematical model to reviewers. However, I've noticed that the documentation for 9 is really for 8. There have been some indications that 10 is coming out with no changes to the documentation since version 8. There is no File | New | CDF (Free or Pro) is 9. The latest CDFs in CDF-Examples are from 2012. This raises a red flag that CDFs are no longer mainstream. Ideally we would like to use a technology that is supported and will stay current with Windows and Apple OS versions. I see that there is a CDF Export and Preview under the File menu. Some of the questions I will be asked by management are: 1. Is CDF considered a legacy technology? If not, will it be available in 10 and future versions - is there a roadmap that can be referenced? 2. If CDF is considered legacy, when do support options expire? 3. Are there any replacements planned from Wolfram that are functionally equivalent to CDFs? If so what are they? 4. What are runtime licensing considerations that should be honored if we use C and C++ as a front-end? CDFs offer an attractive solution - I love what I am seeing in the CDF-Examples - but before committing to CDFs we need to know that this technology is on-going and will stay current with Mathematica and operating systems. Doug Kimzey 2014-07-06T14:44:27Z https://community.wolfram.com/groups/-/m/t/271501 Following the very nice blogpost on the: [Wolfram Blog][1] about Rosetta code, it would be very nice if we could expand---as a community---the number of solved tasks on the Rosetta code website for the [Mathematica Language][2]. The unsolved tasks for Mathematica can be found [here][3]. The number of tasks remaining is: - 145 (june 4th) - 141 (june 5th) - 133 (june 6th) - 130 (june 7th) - 128 (june 14th) - 125 (june 17th) - 120 (june 21st) - 119 (july 4th) Some of the tasks are very easy to implement; others are tricky and very hard (if not impossible). Just now, I solved a couple of problems: - [ABC Problem][4] - [Longest increasing subsequence][5] - [Ludic numbers][6] - [Maximum triangle path sum][7] - [Zebra Puzzle][8] I hope that we can solve some more problems and quickly reduce this number. Furthermore, I hope to start a lively discussion of problem solving and algorithm implementation. As you know, the Wolfram language is very broad and supports many paradigms, so many tasks can be implemented in multiple ways. You should strive to find the most elegant solution (short code, fast run-time). Some problems that should not be too hard to solve are: - [Parse an IP Address][9] - [Rep-string][10] SOLVED! Submitted. - [Nauticall bell][11] - [Word wrap][12] SOLVED! Submitted. (Thanks Marcus Risanger!) - [Fibonacci word fractal][13] SOLVED! Submitted. (Thanks Antonio Marquez-Raygoza!)

The only "real-world" application that meets the specified criteria offered so far (twice) has been Wolfram Alpha (I am not entirely sure that it meets the second criterion - would you choose to develop WA in WL, if you didn't have a bunch of WL experts and a WL development platform at your disposal?). In any event, I am interested in hearing about other real-life applications.... I have a theory, which I am in the process of writing about in a blog post, that other than in applications in mathematics (symbolic logic), Mathematica's primary usefulness is in encouraging a kind of intellectual dilettantism. (Of course, one man's dilettantism is another man's New Kind of Science: i.e. the speculative endeavors of a fertile, creative intellect might readily be mistaken for actual (scientific) achievement by less agile minds.) I don't want this conjecture to be true: I'm as much a buyer of the hype around Mathematica as the next man. But I have noticed that, in practice, Mathematica somehow fails to live up to its apparently unlimited potential for encapsulating creative thought-product across an almost unlimited span of human intellectual endeavor. In my own work in finance, for instance, it has generally proved much less useful than other products such as Matlab. And, in general, when I look at the examples cited by Wolfram in its "customer stories", my reaction to many of them is: "Sure, you can use Mathematica to do that. But why would you, when there are much better alternatives available?". To take one such customer story from the field of 3D CAD, I don't understand why anyone would *prefer* to use Mathematica for such a task, rather than a specialist product like Solidworks. I am aware of applications where the use of Mathematica is fully justified. In my own work, I have used Mathematica to price complex derivatives products, a field in which it excels. Likewise, I am somewhat familiar with Phil Zecker's work at EQA Partners, where he produced an outstanding risk management solution using Mathematica. In both these cases, however, there is no standard, specialized alternative offering in the field of risk management, as there are, for example, in engineering, CAD, app design, or music. In these areas, it seems to me, Mathematica is like a Swiss Army Knife: sure you can use it to dabble in almost anything; but I have screwdrivers, knives and corkscrews that do a better job for their specific purpose. In any event I am looking for counter-examples of real-world applications to refute my hypothesis about Mathematica. By "real-world" I mean specifically applications in which: (i) money changed hands (e.g. a commercial product was sold, or consulting fee earned) ; and (ii) an alternative solution was considered and Mathematica preferred for specific reasons ("it was the only software we could afford or that was available to tackle the job", is not a valid reason to qualify the application as real-world, according to this definition) Jonathan Kinlay 2016-01-17T16:05:55Z https://community.wolfram.com/groups/-/m/t/817719 Dear All, I have a simple scene with some (non-transparent) cubes: ![enter image description here][1] While this motion was relatively fluent (10-20 fps I estimate) in version 10.1, 10.2, 10.3., 10.3.1, it is roughly 0.3 fps for me in version 10.4.
