cupynumeric.diag#

cupynumeric.diag( v: ndarray, k: int = 0, ) → ndarray#

Extract a diagonal or construct a diagonal array.

See the more detailed documentation for cupynumeric.diagonal if you use this function to extract a diagonal and wish to write to the resulting array; whether it returns a copy or a view depends on what version of numpy you are using.

Parameters:

v (array_like) – If v is a 2-D array, return a copy of its k-th diagonal. If v is a 1-D array, return a 2-D array with v on the k-th diagonal.
k (int, optional) – Diagonal in question. The default is 0. Use k>0 for diagonals above the main diagonal, and k<0 for diagonals below the main diagonal.

Returns:

out – The extracted diagonal or constructed diagonal array.

Return type:

ndarray
