[scilab-Users] How to automatically increase matrix name number

[Mike Page]

You need to put all of the line into the string before execstr, like:

-->for i = 1 : 10
-->    newstr = "A = A + matrix" + string(i);
-->    execstr(newstr);
-->end

-->A
 A  =

    10.    20.    30.    40.

(You also have mistyped newstr as mewstr :-)

HTH
Mike.

  Thanks in advance

    All,

    In a loop I would like to create several matrix but their size as well
as their number/name number depend on the file results (they're
automatically created).

    Is it possible that the name number becomes a variable ?

    for i = 1 : n
        creation of A1[] / A2[] / A3[] .... An[]
    end for

    Please note each matrix size may be different


    Thanks for any advice

    Paul

  Once you've ran it, matrix_10 is created and contains [1 2, 3 4].
