SOLVE
Linear Solver for Double Dimensioned Arrays


SOLVE is a MATLAB library which solves a linear system of equations A*x=b using Gauss elimination.

In MATLAB, of course, one can simply type "x = A\b" and get an answer, even if the matrix is ill-conditioned, singular, complex, rectangular (over-determined or under-determined).

Nonetheless, this library is useful because:
