- diagonal(x: array, /, *, offset: int = 0) array ¶
Returns the specified diagonals of a matrix (or a stack of matrices)
x (array) – input array having shape
(..., M, N)and whose innermost two dimensions form
offset (int) –
offset specifying the off-diagonal relative to the main diagonal.
offset = 0: the main diagonal.
offset > 0: off-diagonal above the main diagonal.
offset < 0: off-diagonal below the main diagonal.
out (array) – an array containing the diagonals and whose shape is determined by removing the last two dimensions and appending a dimension equal to the size of the resulting diagonals. The returned array must have the same data type as
