Hello.
I'd like to create a multidim array of, for example, 4-th central moments of matrix g (columnwise). I use for-loops:
K = zeros(m,m,m,m);
for l = 1:m
for k = 1:m
for i = 1:m
for j = 1:m
K(i,j,k,l) = sum(g(:,i) .* g(:,j) .* g(:,l) .* g(:,k));
end
end
end
end
where m is a number of columns in g. How do i evaluate it without for-loops? It takes too much time. thx.
