lib.utils.inv

lib.utils.inv(mat, inv=<function inv>, check=True)

Return inverse of input 2D or 0D (scalar) array mat.

Parameters

• mat (2D array, scalar) – Input matrix to invert.

• inv (callable, default=np.linalg.inv) – Function that takes in 2D array and returns its inverse.

• check (bool, default=True) – If inversion inaccurate, raise a LinAlgError (see _check_inv()).

Returns

toret – Inverse of mat.

Return type

2D array, scalar
