| Here is DatasetAndApply.nb. I have also attached \Dataset_Tutorial.nb , which is another attempt at describing what Dataset does. The current presentation of Dataset[] as a mere display convenience ignores most of what Dataset can do. It is... |
| Dataset[] is an amazingly powerful function with excellent memory use and speed. Dataset[] obtains these virtues at the expense of an idiosyncratic programming language. Once understood, the language is very useful. However, understanding this... |
| Good points. 1. I should have proposed Normal@KeySort[{"a"->3, "b"->20,"c"->1}] to produce a list rather than an association. 2. I should have asked a question, as follows: In option initialization, I usually put option names in... |
| Attached files implement importation of typical (but fictional) commercial data using SemanticImport[], to include the use of very basic data cleansing methodology to improve fidelity of Dataset[] contents. Where possible, information is presented... |
| Assuming that you have Mathematica installed: * Open a notebook ( N) or press the New Document on the Welcome Screen window. * Click on Format * Click on Stylesheet * Click on Utility * Click on Outline That will let you take natural... |
| Sorry about the delay. I usually can't reply on weekdays, thanks to workload. The attached file is pretty much what you need for this job. It is not complete, since I do not understand ECEF and the format is not directly supported by... |
| Answering your question took quite a bit of work. The text below is a summary. We have been in the denial phase for quite some time. My favorite example is Calculus. Calculus courses teach the original development of Calculus, using Leibnitz... |
| 1) The function you posted doesn't seem quite right. See output to: f[x_, y_] := {Sin[x], Cos[y + 1]}; With[{max1 = 10, max2 = 4, x1 = 0, x2 = 2, x1step = 1, x2step = 1}, Module[{counter1 = 1, counter2 = 1}, For[counter1,... |
| Mathematica can be taught on quite a few different levels, depending on the background of who is learning it and why. If the problem is to use existing functions (as if Mathematica were a more powerful replacement for a TI calculator) in a limited... |
