bsr_matrix.setdiag(values, k=0)[source]

Set diagonal or off-diagonal elements of the array.


values : array_like

New values of the diagonal elements.

Values may have any length. If the diagonal is longer than values, then the remaining diagonal entries will not be set. If values if longer than the diagonal, then the remaining values are ignored.

If a scalar value is given, all of the diagonal is set to it.

k : int, optional

Which off-diagonal to set, corresponding to elements a[i,i+k]. Default: 0 (the main diagonal).
