These are related entities, but they aren't exactly interchangeable. A company can have multiple associated Financial entities. So for FinancialData, you will want to give it Financial entities. For CompanyData, you want to give it a Company entity. ...
The D function itself doesn't make use of the Assumptions system, but Simplify does. A few notes: a) It's common to try FullSimplify: D[a*Conjugate[a], x] // ComplexExpand // FullSimplify Although this only gives: E^(2*x)*(1 +...
Yes, DatabinRemove was itself removed (Actually it still works, we just don't guarantee that it will in the future). The original model for the datastructure was append-only and they decided that it was a mistake to deviate from it. The reason...

While you can't use FinancialData with older versions of Mathematica, you might consider using the wolfram cloud, which will (I think) will allow you to try most of it out for free. [https://www.wolframcloud.com/][1] Also, you might contact our...
This is one of my favorite smaller NN projects I've seen. Good job. I have a gut feeling this would be similar to estimating the fractal dimension of the binarized image. https://community.wolfram.com/groups/-/m/t/1025046 A while back,...
In version 12, FinancialData has been updated to return a TimeSeries. So as other people noted, you don't need to manually construct a TimeSeries as you're currently doing. ` stocks = FinancialData["SBUX", "Close", {{2013, 1, 1}, {2013, 8, 1},...
I think you'll have to be more specific to be able to get an answer. Are you familiar with tensor algebra? If so, can you be more explicit about what you're asking for? You're asking how to get an inverse of an order 3 tensor and I don't know that...
When you copy code from the documentation, it sometimes doesn't copy as plain text but copies as a hyperlink to the documentation. That is why you are seeing RefLink. At some point you copied the name of the function from the documentation center and...
Thank you for taking the time to inform us about this issue. I've forwarded the example to the developers. For the majority of cases, you should always avoid programmatically defining down-values of functions. It's impossible in most programming...
