Detailed Description

Virtual interface for LOCA::LAPACK::Group to provide a link to the external code for RHS and Jacobian fills.

This interface is derived from the NOX::LAPACK::Interface and and additionally provides a method for setting problem parameters.

Member Function Documentation

virtual bool LOCA::LAPACK::Interface::computeShiftedMatrix ( double  alpha, double  beta, const NOX::LAPACK::Vector &  x, NOX::LAPACK::Matrix< double > &  A  )

inlinevirtual

Compute shifted matrix alpha*J + beta*M where J is the Jacobian matrix and M is the mass matrix. Returns true if computation was successful.

The default implementation assumes the mass matrix is the identity matrix.

virtual void LOCA::LAPACK::Interface::projectToDraw ( const NOX::LAPACK::Vector &  x, double *  px  ) const

inlinevirtual

Projects solution to a few scalars for multiparameter continuation.

Default implementation is the max norm
