Function Documentation

std::unique_ptr< TCoordinate > HLIB::read_coord

(

const char *

filename

)

Read coord from file filename while the format of the file is detected automatically.

std::unique_ptr< TGrid > HLIB::read_grid

(

const char *

filename

)

Read grid from file filename while the format of the file is detected automatically based on the file content and the file name.

std::unique_ptr< TLinearOperator > HLIB::read_linop

(

const char *

filename

)

Read linear operator from file filename. Currently only the HLIBpro file format supports linear operators.

std::unique_ptr< TMatrix > HLIB::read_matrix

(

const char *

filename

)

Read matrix from file filename while the format of the file is detected automatically. If the file format supports storage of several matrices (or other objects), only the first matrix will be read.

std::unique_ptr< TMatrix > HLIB::read_matrix	(	const char *	filename,
		const char *	matname
	)

Read matrix from file filename while the format of the file is detected automatically. If the file format supports named matrices, the matrix with the name matname will be read. Furthermore, if the file format supports storage of several matrices (or other objects), only the first matrix will be read.

std::unique_ptr< TVector > HLIB::read_vector

(

const char *

filename

)

Read vector from file filename while the format of the file is detected automatically. If the file format supports storage of several matrices (or other objects), only the first vector will be read.

std::unique_ptr< TVector > HLIB::read_vector	(	const char *	filename,
		const char *	vecname
	)

Read vector from file filename while the format of the file is detected automatically. If the file format supports named matrices, the vector with the name vecname will be read. Furthermore, if the file format supports storage of several matrices (or other objects), only the first vector will be read.

void HLIB::write_coord	(	const TCoordinate *	coord,
		const char *	filename
	)

Write coord coord to file filename with automatic choice of file format based on filename suffix:

• hm : HLIBpro format
• mat, m : Matlab format
• coo : SAMG format

void HLIB::write_grid	(	const TGrid *	grid,
		const char *	filename
	)

Write grid to file filename while the format of the file is detected automatically based on the file name.

void HLIB::write_linop	(	const TLinearOperator *	A,
		const char *	filename
	)

Write linear operator A to file filename in HLIBpro format.

void HLIB::write_matrix	(	const TMatrix *	A,
		const char *	filename
	)

Write matrix A to file filename while the format of the file is chosen automatically based upon the filename suffix.

• hm : HLIBpro format
• mat, m : Matlab format
• hb, rb, rua, rsa, psa : Harwell/Boeing format
• amg : SAMG format
• mtx : MatrixMarket format

void HLIB::write_matrix	(	const TMatrix *	A,
		const char *	filename,
		const char *	matname
	)

Write matrix A to file filename while the format of the file is chosen automatically based upon the filename suffix. If the file format supports named matrices, the matrix will be stored under the name matname.

void HLIB::write_vector	(	const TVector *	A,
		const char *	filename
	)

Write vector A to file filename while the format of the file is chosen automatically based upon the filename suffix.

• hm : HLIBpro format
• mat, m : Matlab format
• hb, rb, rua, rsa, psa : Harwell/Boeing format
• rhs, sol : SAMG format
• mtx : VectorMarket format

void HLIB::write_vector	(	const TVector *	A,
		const char *	filename,
		const char *	vecname
	)

Write vector A to file filename while the format of the file is chosen automatically based upon the filename suffix. If the file format supports named matrices, the vector will be stored under the name vecname.
