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.

implicitApply()

void Teko::SmootherLinearOp::implicitApply ( const MultiVector & x, MultiVector & y, const double alpha = 1.0, const double beta = 0.0 ) const

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 . If this operator is reprsented as then
