error in OR matrix for dimension

hello i have two matrix(M & M2) one of them M have 50 row and 32 column and the second one M2 has 50 row and 10 column i want to use OR logical with both of them, i used this code which i found here:

[m,n] = size(M);
   M2 = [zeros(m,3*ceil(n/3)-n),M];
   X = xor(xor(M2(:,1:3:end-2),M2(:,2:3:end-1)),M2(:,3:3:end));

    nM = size(M,2);
   nX = size(X,2);
   n = max(M,X);
   M = [zeros(m,n-nM),M];
   X = [zeros(m,n-nX),X];

 y = X|M

when i try to run the code it give me this error :

    ??? Error using ==> max
    Matrix dimensions must agree.

    Error in ==> ADD at 62
     n = max(M,X);

how to solve this?

n = max(nX,nM);

i have another issue, the output file(txt) give the matrix divided to column (column 1 through 14, column 15 through 28) how to make the matrix came without these column written on top? also the ans is on the top of the file...how to remove it ?

None of the code you've shown has any file writing commands, so everything you mention about the new problem is invisible. Since it's a different issue, however, you should probably pose it in a new thread, anyway.
