I have

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


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.
