DiagonalOperator.derivative¶

DiagonalOperator.derivative(self, point)[source]¶

Derivative of this operator.

For example, if A and B are operators

[[A, 0],
[0, B]]

The derivative is given by:

[[A’, 0],
[0, B’]]

This is only well defined if each sub-operator has a derivative

Parameters

pointelement-like in domain: The point in which the derivative should be taken.
