Subject: can I use bsxfun for this?

Hi

I have 

A=[a11 a12 a13;
     a11 a12 a13;
     a11 a12 a13]

and 

b=[b1 b2 b3]

and would like to compute

[    a11-b1     a12-b2    a13-b3;
     a11-b1     a12-b2    a13-b3;
     a11-b1     a12-b2    a13-b3]

The actual number of columns of A and b is typically  ~100
The number of columns of A und b can vary only together (i.e. 3 columns for A and 3 columns for b)

Thanks for any help.

Peter
