You can use Excel and then import into Maple using the command ExcelTools[Import]

The steps in excel are:

 

 

Now you can use the command ExcelTools[Import]

Hope it helps

 

Problem with subscription label...

I need your guidance. I can not make subscriciones questions to issues of interest to me. Through subscription label. For some time I have to write down the web addresses of interest questions or discussions in which I participated, on a sheet of Notepad. Then go for the checking.

Matlab -> Maple...

herclau 1038

It could be:

restart;

 m := 3;

 L := 10*Matrix(2, m, 1);

L[1 .. 2, 1] := 90;

L;

 v := Matrix(2, m, (i,j)-> convert(L[ .., j], `+`) );

 Hopefully that will help us improve

Gracias

plots:-display(map(plots:-polarplot, a, color = ["Red", "Blue"]))

  

plots:-display(map(plots:-polarplot, a), color = ["Red", "Blue"])
