Under-determined linear systems

Hello,

Can anyone tell me whether NR has a solve function that can cope with systems of linear equations where there are more unknowns than equations, i.e. matrix A in Ax = b has more columns than rows?

Ideally it would use SVD, but to pick out one solution out of the infinite number of possible ones, will look for x with the smallest norm.

Thanks
