Linear Equations

The program solves matrix equation $A x = b$, where $A$ is the coefficient matrix of $m \times n$ set of simultaneous linear equations, and $b$ is a column vector (or matrix with multiple columns). If $A$ represents an overdetermined system, then the least-square set of $x$ is obtained, i.e. that minimizes $||A x - b||^2$.
