Detailed Description

This class applies an operator as a smoother. The main idea being that a residual is used and corrected to get a Gauss-Seidel like method.

virtual

Perform a matrix vector multiply with this implicitly defined blocked operator.

The apply function takes one vector as input and applies a linear operator. The result is returned in $y$ . If this operator is reprsented as $M$ then $y = \alpha M x + \beta y$
