tril
(m, k=0)[source]¶ Make a copy of a matrix with elements above the kth diagonal zeroed.
LAX-backend implementation of
tril()
. Original docstring below.Parameters: - m (array_like) – Matrix whose elements to return
- k (int, optional) – Diagonal above which to zero elements. k == 0 is the main diagonal, k < 0 subdiagonal and k > 0 superdiagonal.
Returns: tril – Return is the same shape and type as m.
Return type: ndarray
Examples
>>> from scipy.linalg import tril >>> tril([[1,2,3],[4,5,6],[7,8,9],[10,11,12]], -1) array([[ 0, 0, 0], [ 4, 0, 0], [ 7, 8, 0], [10, 11, 12]])
