element by element matrix multiplication in Matlab

Question

So I have the following matrices:

A = [1 2 3; 4 5 6];
B = [0.5 2 3];

I\'m writing a function in MATLAB that will allow me to multiply a vec

Answer 1

MATLAB already has functionality to do this in the bsxfun function. bsxfun will take two matrices and duplicate singleton dimensions until the matrices are the same size, then perform a binary operation on the two matrices. So, for your example, you would simply do the following:

C = bsxfun(@times,mat,vec);
