Function Documentation

mirml_initialize()

int mirml_initialize

(

void

)

Initialization of the MirML library.

Note

This function should be called first before using other MirML functions.

mirml_matrix_fprintf()

void mirml_matrix_fprintf	(	const mirml_matrix_t *	mat,
		FILE *	fp,
		const char *	format,
		unsigned int	nline
	)

Print matrix elements.

Parameters

[in]	mat	Pointer to the matrix structure.
[in]	fp	File handle.
[in]	format	User-defined format (as for fprintf) for elements. If NULL, then default format is used.
[in]	nline	Maximal number of column indices per line. If 0, then default number is used.

mirml_terminate()

void mirml_terminate

(

void

)

Termination of the MirML library.

Note

No MirML functions should be used after calling this function.

mirml_vector_fprintf()

void mirml_vector_fprintf	(	const mirml_vector_t *	vec,
		FILE *	fp,
		const char *	format,
		unsigned int	nline
	)

Print vector elements.

Parameters

[in]	vec	Pointer to the vector structure.
[in]	fp	File handle.
[in]	format	User-defined format (as for fprintf) for elements. If NULL, then default format is used.
[in]	nline	Maximal number of elements per line. If 0, then default number is used.
