| You are not alone, I am lost somewhere between Wolfram Language, math and physics 97% of the time. I used ConstantArray as a easy way to generate repeated frequency values the length of the mass span. ConstantArray[x,4] -> {x,x,x,x} so I just... |
| Thanks for pressing the question, Ronald. I gave up on the iPad app years ago... must be a retired-guy thing. My take was that there is a gap between what you and I assumed the usage scenario to be and what the developers assumed it would be.... |
| Thanks for posting interesting work. I wonder if you can point me towards tutorials or texts that would explain how the kernel in your recurrence relates to the word problem. After 20 years with Mathematica, I have learned how to do tensor... |
| Howdy from an old-timer who has no idea how to use the new-fangled stuff since v4 days. I can't even frame the question other than say I saw an interesting post on evolutionary graphs and clicked on it and it opened something in the cloud without any... |
| I must admit to being a bit surprised that my initial question still garners attention. As a veteran of first silicon validation for 386, 486 and Pentium plus three IPO's I have made my share of mistakes. I recall being embarrassed about delivering... |
| Thanks Rohit. I looked at Wikipedia and discovered GitHub started when I retired. No wonder I hadn't heard of it over my 50 year career. Good to see a universal tool appear... a lot to relearn! |
| Wow, that was simple... never thought about padding right or left. Thanks a lot! I just figured out how to treat other neighborhood sizes: With[{r = Range@5, n = 4}, Partition[PadRight[r, Length@r + n - 1, r], n, 1]] Any idea about introductory... |
| Complexity Science seems to be advancing frontiers in many conventional subjects. For example, network (graphs) have become important tools in chemistry, biology and sociology to name a few. Ergodic theory, Tsallis entropy and non-Gaussian statistics... |
