virtual void itk::fem::LinearSystemWrapperItpack::Solve ( void  )
virtual

Solves the linear system and creates the solution vector, which can later be accessed via GetSolutionValue(i,SolutionIndex) member function. Here all the major processing is done with calls to external numeric library.

Note
This function can only be called after the linear system was properly assembled.

Implements itk::fem::LinearSystemWrapper.

void itk::fem::LinearSystemWrapperItpack::SuccessiveOverrelaxation ( )
inline

Set numerical solving method to successive over-relaxation

Swaps access indices of any 2 matrices in the linear system

Parameters
matrixIndex1index of a matrix to swap
matrixIndex2index of matrix to swap with

Implements itk::fem::LinearSystemWrapper.

virtual void itk::fem::LinearSystemWrapperItpack::SwapSolutions ( unsigned int  solutionIndex1,
unsigned int  solutionIndex2 
)
