Closes #18153. numpy.tril¶ numpy.tril (m, k=0) [source] ¶ Lower triangle of an array. 36. k = 0 (the default) is the main diagonal, k < 0 is below it and k > 0 is above. Diagonal offset (see tril for details). New in version 1.4.0. X = X + X. Notes. lower triangular part starting at the main diagonal, and one starting two Les blocs des listes les plus internes sont concaténés (voir concatenate) le long de la dernière dimension (-1), puis concaténés le long de l'avant dernière dimension (-2), et ainsi de suite jusqu'à ce que la liste la plus externe soit atteinte. By default m is taken equal to n. The indices for the triangle. array([[0., 2., 3. Assume mask_func is a function that, for a square array a of size (n, n) with a possible offset argument k, when called as mask_func(a, k) returns a new array with zeros in certain locations (functions like triu or tril do precisely this). It will act on nd-arrays (along a specified axis); and also will look up multiple entries in a vectorized manner as opposed to a single item at a time. For a.ndim = 2 this is the usual diagonal, for a.ndim > 2 this is the set of indices to access a[i, i, ..., i] for i = [0..n-1].
