Multiply image with vector

Hello is there a function in Matlab where I could multiply an NxM image with a vector ?

I would do something like this :

>> vec = [1,2,3];
>> vec = reshape(vec,[1,1,3]);
>> img = [1,1;1,1];
>> imgrgb = dimmulty(3,vec,img);//imgrgb is a 2x2x3 image

What I am searching is the dimmulty function !

bsxfun does exactly that :)

>> bsxfun(@times,vec,img)

(I use this really frequently for applying operations to RGB images)
