Hi,

I've got an array, say with i,jth entry = A_ij, and a vector, say with jth
entry= v_j. I would like to multiply each column of the array by the
corresponding vector component, i,e. find the array with i,jth entry

A_ij * v_j

This seems so basic but I can't figure out how to do it without a loop.
Any suggestions?

Michal.
