def xxminv(a, b, solve=True, return_inverted=False)

Matrix inversion with accompanying solution of linear equations if requested.

Parameters

a : float, array: n x n matrix to be inverted
b : float, array: rhs of Ax=b if solve is True.
return_inverted : bool: If True also return the inverted matrix. The default is False.

Returns

x : float, array: The solution vector
ainv : float, array: The inverted matrix a' of a. Only if return_inverted is set to True.

Notes

Calls a fortran based shared object file - not pure python.
