Member Function Documentation

void g2o::MatrixStructure::alloc	(	int	n_,
		int	nz
	)

allocate space for the Matrix Structure. You may call this on an already allocated struct, it will then reallocate the memory + additional space (double the required space).

void g2o::MatrixStructure::free ( )

Definition at line 68 of file matrix_structure.cpp.

int g2o::MatrixStructure::nzMax ( ) const [inline]

max number of non-zeros blocks

Definition at line 49 of file matrix_structure.h.

bool g2o::MatrixStructure::write ( const char * filename ) const

Write the matrix pattern to a file. File is also loadable by octave, e.g., then use spy(matrix)
