I corrected the initial problem with the matrix dimentions of w and xt by inverting the matrix w (w=w') but now when i try to run the program i get:

"Warning: Integer operands are required for colon operator when used as
index
> In mystft at 9

Error using horzcat
Dimensions of matrices being concatenated are not consistent.

Error in mystft (line 19)
xtwz = [xtw(Mo2+1:M), zp, xtw(1:Mo2)]; % windowed, zero padded"

where line 9 is: " zp = zeros(N-M,1); % zero padding (to be inserted) "
