Member Function Documentation

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

Insert a new row

Parameters:
new_rowThe new sparse measurement row to add.
new_rNew 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_rowThe new sparse measurement row to add.
new_rNew 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:
numNumber 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.
