dpnp.tril

dpnp.tril(m, /, *, k=0)

Lower triangle of an array.

Return a copy of an array with elements above the k-th diagonal zeroed.

For full documentation refer to numpy.tril.

Parameters:

• m ({dpnp_array, usm_ndarray}, shape (…, M, N)) -- Input array.

• k (int, optional) -- Diagonal above which to zero elements. k = 0 (the default) is the main diagonal, k < 0 is below it and k > 0 is above.

Returns:

out -- Lower triangle of m, of same shape and dtype as m.

Return type:

dpnp.ndarray of shape (N, M)

Examples

>>> import dpnp as np
>>> m = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]])
>>> np.tril(m, k=-1)
array([[ 0,  0,  0],
       [ 4,  0,  0],
       [ 7,  8,  0],
       [10, 11, 12]])
