Gauss Elimination for Simplex algorithm

This code presents the Gauss Elimination process to solve basic variables and objective value for solving Simplex problems.

Gauss elimination is an effective tool for solving a linear system of equations. Applying Simplex algorithm, we are involving a system of equations with more unknowns than the number of equation. To solve such undetermined system, we then divide the variables to known (non-basic variables set to zeros) and basic variables to be solved.
