matrix and vector multiplication without for loop

Hi, I have 3 matrices "X" is m x n matrix and "Y" is m x 1 column vector, I want to multiply each column of X by the vector Y and calculate the sum of each multiplied column and put them in column vector "G" which is n x 1. Is there any way to do this without using for loops (vectorized solution) ?

Answer 1

[Roger Stafford]

 G = X.'*Y;

This is so cool! Nice hack!

Answer 2

[Azzi Abdelmalek]

n=4;
m=3;
X=rand(m,n); % Example
Y=rand(m,1);
G=sum(bsxfun(@times,X,Y))'
