We can also get the L and U matrices used in the LU decomposition using the scipy package. from scipy.linalg import lu P, L, U = lu(A) print('P:\n', P) print('L:\n', L) print('U:\n', U) print('LU:\n',np.dot(L, U)) The result will be : P: [[0. 0. 1.] [0. 1. 0.] [1. 0. 0.]] L: [[ 1. 0. 0. ] [-0.25 1.
