Assignment Help:

Write a C function to solve the system of linear equations A x = y where A is an N by N matrix in the format of pointer-to-pointers and y is a vector in the format of a pointer. The function should return a pointer to the answer vector x. Your function should have the prototype:

double *Gaussian(double **,double *, int).
The function should implement the Gaussian Elimination Algorithm with Partial Pivoting.
Test your function on the system:
