This function in my code is a bottleneck. Is it possible to make it run faster?
x and y are vectors of the same length and out is a matrix containing the power sum of x and y.
function [out] = powerSum2(x,y,order)
out = zeros(order+1);
for ii = 0:order
for jj = 0:order
out(ii+1,jj+1) = sum(x.^ii.*y.^jj);
end
end
end
