You are to implement Gaussian Elimination as presented in C++.

You should be able to load from a file the contents of a problem:

N ///sets the size of your problem

A ///N*N values in the matrix A

b ///N values in the vector b

using dynamic matrix/vector allocation e.g.

double * b;

double * x;

double ** A;

b = new double [N];

x = new double [N];

A = new double *[N];
