numpy.linalg.LinAlgError — NumPy v1.11 Manual (original) (raw)

exception numpy.linalg.LinAlgError[source]¶

Generic Python-exception-derived object raised by linalg functions.

General purpose exception class, derived from Python’s exception.Exception class, programmatically raised in linalg functions when a Linear Algebra-related condition would prevent further correct execution of the function.

Examples

from numpy import linalg as LA LA.inv(np.zeros((2,2))) Traceback (most recent call last): File "", line 1, in File "...linalg.py", line 350, in inv return wrap(solve(a, identity(a.shape[0], dtype=a.dtype))) File "...linalg.py", line 249, in solve raise LinAlgError('Singular matrix') numpy.linalg.LinAlgError: Singular matrix
