Enumerators

enumerator	::	MM_COORDINATE	=	1	Sparse coordinate file.
enumerator	::	MM_ARRAY	=	2	Dense array file.
enumerator	::	MM_REAL	=	1	Real data being read in.
enumerator	::	MM_INTEGER	=	2	Integer data being read in.
enumerator	::	MM_COMPLEX	=	3	Complex numbers being read in.
enumerator	::	MM_PATTERN	=	4	Just a pattern of non zeros.
enumerator	::	MM_GENERAL	=	1	File lacks symmetry.
enumerator	::	MM_SYMMETRIC	=	2	File is symmetric
enumerator	::	MM_SKEW_SYMMETRIC	=	3	File is skew symmetric.
enumerator	::	MM_HERMITIAN	=	4	File is hermitian.

Functions

public function ParseMMHeader(line, sparsity_type, data_type, pattern_type) result(no_error)

Parse a matrix market header.
