I have two matrices A (3,3,x) and B (3,3) where x is a variable, known value and typically on the order of thousands. I need to compute the matrix multiplication of these two, I know this can be done by
function [ out ] = mat_mult( A,B )
[~,~,np] = size(A);
out = zeros(size(A));
out(:,:,i) = A(:,:,i)*B;
but I figure there is a more efficient way to do this than for loops, especially for MATLAB. Unforunately, I am not quite sure how to vectorize this.
