Hi everybody I apologize for my ignorance but I want your help. I want to create a ones(3) matrix from the zeros(3) matrix by having all the combinations with 0 and 1.

What I want is every time that I change a 0 with a 1 to know how many matrixes I will have and which ones when I change two 0 with two 1 to have the matrices and so on until change all 0 with 1where the final matrix it will be [111;111;111]

Do you mean that you want every possible combination of 3x3 matrix filled with 0 or 1? The following is pretty obfuscated code, but it is fast and easy:
A = reshape((dec2bin(0:2^9-1) - '0')',3,3,[]);
A is a 3x3x512 array, where each "slice" in dimension 3 is one possible matrix.

I'm not sure I understand what you are asking. What I posted is a line of MATLAB code, and you can put it in an m file like any other MATLAB code. It is no different from putting
B = 3 + 6;
in an m file.
