can help me with this simple code?

I have a list of string (str_1,str_2.......str_n) an a matrix called "A" of string

str_1 str_2
str_1 str_4
... ...

I want to assign for each "str" a number, for example

str_1=1
str_2=2
....

to have the matrix "A":

1 2
1 4

"A" cannot be a matrix of strings, because this is not valid in Matlab. Do you mean a cell string?

Don't do this!

You find hundrets of concerning threads in this forum, e.g. http://www.mathworks.com/matlabcentral/answers/269836-hi-i-want-to-define-repetitive-vectors-from-notepad-data-using-loop

If you have the Symbolic Toolbox, you can do this:

str = sym('str_%d', [1 n]);
A = [str(1), str(2)
     str(1), str(4)];

subs(A, str, [1 2 17 4])

you might even be able to refer to str_1 directly in A; I would need to test that.
