Member Function Documentation

void isam::SparseSystem::add_row	(	const SparseVector &	new_row,
		double	new_r
	)		`[virtual]`

Insert a new row

Parameters:

new_row	The new sparse measurement row to add.
new_r	New right hand side entry.

Definition at line 86 of file SparseSystem.cpp.

int isam::SparseSystem::add_row_givens	(	const SparseVector &	new_row,
		double	new_r
	)		`[virtual]`

Insert a new measurement row and triangulate using Givens rotations

Parameters:

new_row	The new sparse measurement row to add.
new_r	New right hand side entry.

Returns:: Number of Givens rotations applied (for analysis).

Definition at line 95 of file SparseSystem.cpp.

void isam::SparseSystem::append_new_rows ( int num ) [virtual]

Append new rows to matrix.

Parameters:

num	Number of rows to add.

Reimplemented from isam::SparseMatrix.

Definition at line 81 of file SparseSystem.cpp.

void isam::SparseSystem::apply_givens	(	int	row,
		int	col,
		double *	c_givens = `NULL`,
		double *	s_givens = `NULL`
	)		`[virtual]`

Note: While rows are passed in, the rhs is required to already contain the new entry - necessary because we cannot change the signature of the function.

Reimplemented from isam::SparseMatrix.

Definition at line 71 of file SparseSystem.cpp.

const SparseSystem & isam::SparseSystem::operator= ( const SparseSystem & mat )

Definition at line 61 of file SparseSystem.cpp.

const Eigen::VectorXd& isam::SparseSystem::rhs ( ) const [inline]

Definition at line 46 of file SparseSystem.h.

void isam::SparseSystem::set_rhs ( const Eigen::VectorXd & rhs ) [inline]

Definition at line 47 of file SparseSystem.h.

VectorXd isam::SparseSystem::solve ( ) const [virtual]

Solve equation system by backsubstitution.

Returns:: Solution for x in Rx=b'

Definition at line 119 of file SparseSystem.cpp.
