// Purpose: Compute approximations to the solution x of Ax = b and an
//    approximations of the inverse of A. In both case the system (m x n) can be
//    square (m = n), over-determined (m > n) and under-determined (m < n).
// Global functions:
//    LSS(): General entry for linear system solver.
//    INV(): General entry for matrix inversion.
