public BigRational[] solve(BigRational[] b)
                    throws OperationNotSupportedException,
InconsistentLinearSystemException

Solves the linear system using Gaussian elimination with partial pivoting

Specified by:

solve in interface SolverInterface

Overrides:

solve in class Solver

Parameters:

b - The vector b of the linear system Ax = b

Returns:

A vector containing the solutions of the linear system

Throws:

OperationNotSupportedException - Thrown when the system cannot be solved due to bad vector b size

InconsistentLinearSystemException - if the operation cannot be completed
