I have a 3D array (a) such that size(a) = [n,n,m]. I also have a vector (v) of length(v) = m. I would like to multiply each element from my vector with each 2D matrix in my array. Is there a way to do this without a for loop. To clarify, using a for loop it would be:
for i = 1:m
b(:,:,i) = v(i)*a(:,:,i);
end
