Detailed Description

This class implements a utility that allows you to print a grid to file.

These files can be plotted with gnuplot.

Member Function Documentation

◆ printGrid()

void sgpp::base::GridPrinter::printGrid	(	DataVector &	alpha,
		std::string	tFilename,
		size_t	PointsPerDimension
	)

virtual

Print the grid with its function to a file; front end.

Parameters

alpha	the coefficients of the grid's ansatzfunctions
tFilename	absolute path to the file the grid is written into
PointsPerDimension	specifies how many functions evaluations in every dimension should be calculated

◆ printSparseGrid()

void sgpp::base::GridPrinter::printSparseGrid	(	DataVector &	alpha,
		std::string	tFilename,
		bool	bSurplus
	)

virtual

Prints the Grid Points of the Sparse Grid either with their node basis value or their hierarchical surplus.

Parameters

alpha	the coefficients of the grid's ansatzfunctions
tFilename	absoulte path to the file the grid is written into
bSurplus	specifies whether the surplus (true) or the node basis value (false) is written

◆ printSparseGridExpTransform()

void sgpp::base::GridPrinter::printSparseGridExpTransform	(	DataVector &	alpha,
		std::string	tFilename,
		bool	bSurplus
	)

virtual

Prints the Grid Points of the Sparse Grid either with their node basis value or their hierarchical surplus.

The coordinates of the grid points are pushed the exp function. So log transformed grids can be plotted in cartesion coordinates.

Parameters

alpha	the coefficients of the grid's ansatzfunctions
tFilename	absoulte path to the file the grid is written into
bSurplus	specifies whether the surplus (true) or the node basis value (false) is written
