scipy.sparse.dia_matrix.

power

dia_matrix.power(n, dtype=None)

This function performs element-wise power.

Parameters:

nscalar

n is a non-zero scalar (nonzero avoids dense ones creation) If zero power is desired, special case it to use np.ones

dtypeIf dtype is not specified, the current dtype will be preserved.

Raises:

NotImplementedErrorif n is a zero scalar

If zero power is desired, special case it to use np.ones(A.shape, dtype=A.dtype)
