PrecisionOpCs Class Reference

#include <PrecisionOpCs.hpp>

Inheritance diagram for PrecisionOpCs:

Detailed Description

This class is just a specialization of PrecisionOp when the shift Operator is built with sparse matrices and therefore algebra can be performed with Cholesky. It allows to return the precision matrix as a Sparse Matrix.
