i want to make a user input file where the matrix would be loaded into matlab

Hi i want a text file (txt-file) where the user eg. writes

txt file start:

A = 30;

IX = 10;

% A =

[ 1 2 3 IX

5 6 7 IX]

% B =

[ 1 2 3 A

5 6 7 A]

txt file end

and when you load this txt files in the matlab then i want the matlab to know what the matrix should look like:

% A =

[ 1 2 3 10

5 6 7 10]

% B =

[ 1 2 3 30

5 6 7 30]

Just make it a .m file (and remove the %).

Of course, don't use A both as the constant 30 and as the name of a matrix. You can use any name you want for your variables you don't have to limit yourself to the 26 letters of the alphabet, and you certainly don't have to reuse the same name for different purposes.

just one question, is it possible to do it from txt. file ?
