const int * isam::OrderedSparseMatrix::a_to_r

(

)

const [virtual]

Return variable ordering

Returns:

Array of integers that specifies for each column in A which column it now corresponds to in R.

Definition at line 158 of file OrderedSparseMatrix.cpp.

void isam::OrderedSparseMatrix::append_new_cols

(

int

num

)

[virtual]

Expand matrix to include new columns.

Parameters:

num	Number of columns to add.

Reimplemented from isam::SparseMatrix.

Definition at line 134 of file OrderedSparseMatrix.cpp.

void isam::OrderedSparseMatrix::import_rows_ordered	(	int	num_rows,
		int	num_cols,
		SparseVector_p *	rows,
		int *	r_to_a
	)

Import externally allocated rows, and also set the ordering.

Parameters:

num_rows	Number of rows of new matrix.
num_cols	Number of columns of new matrix.
rows	Array of SparseVector of length num_rows.
r_to_a	Variable ordering.

Definition at line 127 of file OrderedSparseMatrix.cpp.

const OrderedSparseMatrix & isam::OrderedSparseMatrix::operator=

(

const OrderedSparseMatrix &

mat

)

Assignment operator.

Parameters:

mat	Right-hand-side matrix in assignment

Returns:

self.

const int * isam::OrderedSparseMatrix::r_to_a

(

)

const [virtual]

Return inverse variable ordering

Returns:

Array of integers that specifies for each column in R which column it originally came from in A.

Definition at line 162 of file OrderedSparseMatrix.cpp.

void isam::OrderedSparseMatrix::set_row	(	int	row,
		const SparseVector &	new_row
	)		[virtual]

Replace the given row. Also reorders the new vector according to internal ordering.

Parameters:

row	Number of row to replace.
new_row	New row vector.

Reimplemented from isam::SparseMatrix.
