Sorry, Zhao, but your questions and code are a nightmare. I feel you want to do some kind of restructuring code, actually, just rename variables. This is a trivial task and done with Find/Replace (Edit-menu > Find... within the Wolfram desktop). Just...
I dont believe that. Your Code: ClearAll[x]; Array[Symbol["x" ToString@FromDigits@{##}] &, {3}] (* ==> {x1,x2,x3} *) is correct. Maybe: ClearAll[x]; Array[Symbol["x" ToString[#]] &, 3] (* ==> {x1,x2,x3} *) ...
This happened with: - Windows 10 Pro (64-bit), 21H2, Build 19044.1949 - Wolfram|One 13.1.0 - Intel(R) Core(TM) i7-3840QM CPU @ 2.80GHz 2.80 GHz - 16 GB RAM I just tried it on: - Windows 11 Pro (64-bit), 21H2, Build 22000.918 -...
> Another issue regarding language is the almost exclusive use of English. I may be wrong, but Mathematica is one of the few software systems that addresses this: they have what are essentially subtitles for their code. You still have to type the...
I want to assign a keyboard shortcut, say "Shift+Ctrl+I", to apply the style "InlineFormula" to the current selection. (I have changed this style, but this does not matter here). I know that this is possible by modifying the...
Yes Hans, that's the problem. Actually, it's not severe. What I'm doing is: - Prepare the list of all cells - Use CreateDocument with that complete list. Actually, I was just wondering where this "dirty-flag" is hidden, or how it can be...
OK, Daniel. I can live with it. It needs just omitting the default for the other parameters.
This works indeed, Mariusz (within 0,06 secs). **But why?** I had never thought that solving in Complex would be easier than within Reals. But anyway this is a valid solution. I can apply the Reals-condition later to the result.
Robert, this solution with NumericQ works indeed. I had in mind that NumericQ was Listable, but it isn't. MatchQ[{1, {20, 21}, 300}, {Repeated[_?NumericQ, 3]}] (* False *) But your original proposal does not really work since AtomQ...
