Congratulations on solving this problem. For future endeavours you might consider the following: (1) many common calculations already have dedicated functions available to compute them in MATLAB; (2) for generality you might have to initialise y=-Inf, not y=0; (3) for generality you might have to iterate over 1:size(x,#), not 1:2.
