Find out if a matrix is positive definite with NumPy

How can I find out if a matrix is positive definite? My matrix is a NumPy matrix. I was expecting to find any related method in the NumPy library, but I didn't have any success.
You can also check if all the eigenvalues of matrix are positive. If so, the matrix is positive definite: import numpy as np def is_pos_def(x): return np.all(np.linalg.eigvals(x) > 0)
