S = repmat('*', n, n)   % A square

% Or:
S = '';
S(1:n, 1:n) = '*';

For a square, you have to set the elements (2:n-1, 2:n-1) to the space afterwards.

ıt works, thank you so much! But I couldnt find how to print an empty square

[Jan]

See this:

S = repmat('*', n, n);
S(2:3, 3:4) = '#'

[themh sra]

this code doesnt work for an empty square

[Jan]

Which code does not run for what input? What exactly is "an empty square"? n=0?

What does "doesn't work" mean? Please post the code you use and the error message you get.

I showed how to insert # characters as a rectangular shape. I assume, that you can replace '#' by ' ' and 2:3 by 2:n-1 .
