Detailed Description

template<typename Real = double>
class KKT_Operator< Real >

KKT_Operator to be used with dealii::SolverBase class.

Member Function Documentation

print()

template<typename Real = double>

void KKT_Operator< Real >::print ( const dealiiSolverVectorWrappingROL< Real > &  vector_format )

inline

Print the KKT system if the program is run with 1 MPI process.

If more than 1 MPI process is used, we can't print out the matrix since the information is distributed

Definition at line 114 of file kkt_operator.hpp.

Tvmult()

template<typename Real = double>

void KKT_Operator< Real >::Tvmult ( dealiiSolverVectorWrappingROL< Real > &  dst, const dealiiSolverVectorWrappingROL< Real > &  src  ) const

inline

Application of transposed KKT matrix on vector src outputted into dst.

Same as vmult since KKT matrix is symmetric.
