(

)

Transform an operator by pointwise computation of the matrix inverse.

Parameters

op	The operator to invert poitwise (should be a constant, or 0-linear MultilinearOperator or SumOperator)

Given an 0-linear operator op this returns another 0-linear operator, where a pointwise transformation is applied in the associated function space range. If op is a constant, the transformation is applied directly. The pointwise transformation computes the matrix inverse.

Since this is a nonlinear operation, it is only available if op is 0-linear.
