MATLAB supports (and encourages) vectorized operations on vectors and matrices.
For example, suppose we have
m matrices and we want
C to be the element-wise product of the corresponding elements (i.e.,
C(i,j) = A(i,j)*B(i,j)).
The un-vectorized way, using nested loops is as follows:
C = zeros(n,m); for ii=1:n for jj=1:m C(ii,jj) = A(ii,jj)*B(ii,jj); end end
However, the vectorized way of doing this is by using the element-wise operator
C = A.*B;
