Parameters: arr: array_like. numpy.tril_indices_from ¶ numpy.tril_indices_from(arr, k=0) [source] ¶ Return the indices for the lower-triangle of arr. Examples . Diagonal offset (see triu for details). mask_func : [callable] A function whose call signature is similar to that of triu, tril. generic function accepting an arbitrary mask function. numpy.tril_indices, numpy.tril_indices¶. numpy.triu_indices ¶ numpy.triu_indices(n, k=0, m=None) [source] ¶ Return the indices for the upper-triangle of an (n, m) array. tril_indices similar function, for lower-triangular. Syntax : numpy.mask_indices(n, mask_func, k = 0) Parameters : n : [int] The returned indices will be valid to access arrays of shape (n, n). k: int, optional. Notes. tril_indices() might be the obvious approach here that generates the lower triangular indices and then you can use those to set those in input array to NaNs. The returned tuple contains two arrays, New in version 1.4.0. Random sampling (numpy.random) index; next; previous; numpy.random.choice ¶ numpy.random.choice (a, size=None, replace=True, p=None) ¶ Generates a random sample from a given 1-D array. numpy.tril_indices_from(arr, k=0) [source] Return the indices for the lower-triangle of arr. Syntax : numpy.mask_indices(n, mask_func, k = 0) Parameters : n : [int] The returned indices will be valid to access arrays of shape (n, n). See tril_indices for full details. k: int, optional. Python numpy.tril_indices_from() Examples The following are 14 code examples for showing how to use numpy.tril_indices_from(). Voir tril_indices pour plus de détails. m: int, optional. Improve this answer. Parameters-----arr : array_like: The indices will be valid for square arrays whose dimensions are: the same as arr. Parameters m array_like, shape (M, N) Input array. The row dimension of the arrays for which the returned triu (m[, k]) Upper triangle of an array. k int, optional. tril_indices_from (arr[, k]) Return the indices for the lower-triangle of arr. Return a copy of a matrix with the elements below the k-th diagonal zeroed.. Next topic. numpy.tril_indices_from(arr, k=0) [source] Renvoie les indices pour le triangle inférieur d'arr. indices will be valid. Notes. numpy.triu¶ numpy.triu (m, k=0) [source] ¶ Upper triangle of an array. 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). The size of the arrays for which the returned indices will be valid. This problem can be solved efficiently using the numpy_indexed library (disclaimer: I am its author); which was created to address problems of this type. Return a copy of an array with elements above the k-th diagonal zeroed. Python numpy.tril_indices()Examples The following are 30code examples for showing how to use numpy.tril_indices(). numpy.triu_indices, Return the indices for the upper-triangle of an (n, m) array. numpy.tril_indices, numpy.tril_indices¶. numpy.tril_indices () function return the indices for the lower-triangle of an (n, m) array. triu, tril. Return the indices for the lower-triangle of an (n, m) array. array([[0., 2., 3. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. lower triangular part starting at the main diagonal, and one starting two Try numpy.triu (triangle-upper) and numpy.tril (triangle-lower). lower triangular part starting at the main diagonal, and one starting two Notes. latest Tutorials. New in version 1.7.0. See triu_indices for full det_来自Numpy 1.10，w3cschool。 Diagonal offset (see tril for details). In this article we will discuss how to get the maximum / largest value in a Numpy array and its indices using numpy.amax(). The following are 30 code examples for showing how to use numpy.tril_indices(). numpy.tril_indices (n, k=0, m=None) [source] ¶ Return the indices for the lower-triangle of an (n, m) array. m: int, optional. This returns a tuple of indices that can be used to access the main diagonal of an array a with a.ndim >= 2 dimensions and shape (n, n, ..., n). ( [ [ 0., 0., 0. ] ] ) the.
