OperatorMatrix Struct Reference

TransformMatrix represents finite difference, collocation or Galerkin operator matrices. These consist of L-shaped blocks in the upper left and the lower right corner as well as generic coefficients for the inner region. More...

Public Methods

OperatorMatrix ()

default constructor.

void MatVec (double *T, IndexSet *IT, int *BCT, double *F, IndexSet *IF, int *BCF, int level, int clearflag, double DX, doubleBuffer *buf)

perform an (adaptive) matrix vector multiply (*T) = (*this)* (*F).
Parameters:

T result

IT index set for components of T which shall be computed

F vector

IF index set for components of F which may be used

level the level index of

clearflag if ==0 compute (*T) += (this*)*(*F)

doubleBuffer auxiliary array

DX=XE-XA length of computatioal domain.

void MatVec2 (double *T, IndexSet *IT, int *BCT, double *F, IndexSet *IF, int *BCF, int level, int clearflag, double DX, doubleBuffer *buf)

special multiply for finite difference Methods here also at the boundarties of inner intervals the boundary modified FD stencils are used in order to preserve the order of consistency.

void MatTVec (double *T, IndexSet *IT, int *BCT, double *F, IndexSet *IF, int *BCF, int level, double DX, doubleBuffer *buf)

perform an (adaptive) matrix vector multiply (*T) = (*this)^T * (*F).

void Print ()

print some informations.
