This program contains a function that takes a matrix A and a vector b and prints the vector x from Ax = b. If the matrix A is not invertible, the function will print "This matrix is not invertible".

The user needs to call the gauss_eli function and pass in the matrix A and a vector b as nested list and list. The result will be printed to the console.

The user needs to install Python and the NumPy library. gausseli copy.py contains the function gauss_eli, which performs the Gaussian Elimination.
