Detailed Description

representing the structure of a matrix in column compressed structure (only the upper triangular part of the matrix)

Definition at line 36 of file matrix_structure.h.

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).

Definition at line 55 of file matrix_structure.cpp.

void g2o::MatrixStructure::free ( )

Definition at line 78 of file matrix_structure.cpp.

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

max number of non-zeros blocks

Definition at line 60 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)

Definition at line 88 of file matrix_structure.cpp.
