I have 2 matrixs: pa and win and i would like to create a matrix pTW where: if in pa is not 0 set to pTW a value from win.
pTW(pa ~= 0) = win ; this does not work
pa =
0 0 0 0 0 0 0 0 0 0 0 0

You need to also select those specific elements from win, and also create pTW of the correct size, if it does not exist.
pTW = zeros(size(pa));
pTW(pa ~= 0) = win(pa ~= 0);
