One way to solve such a problem is to ask for the solution x with the smallest norm. The solution of min { x T x: A x = b } can be obtained via the Lagrangian, and corresponds to the solution of: ( 2 I A T A O) ( x λ) = ( 0 b) For the general solution, you could compute the LU decomposition of A, and take it from there.
