Constructor & Destructor Documentation

SparseMatrix::SparseMatrix

(

)

Default constructor.

SparseMatrix::SparseMatrix	(	bool	isColumnMajor_,
		int	startSize,
		int	valueSize
	)

Constructor.

Parameters:

	isColumnMajor	holds whether the coefMatrix (AMatrix) holding linear program data is stored by column. If false, the matrix is stored by row.
	startSize	holds the size of the start array.
	valueSize	holds the size of the value and index arrays.

Member Data Documentation

bool SparseMatrix::bDeleteArrays

bDeleteArrays is true if we delete the arrays in garbage collection set to true by default

Definition at line 48 of file OSDataStructures.h.

bool SparseMatrix::isColumnMajor

isColumnMajor holds whether the coefMatrix (AMatrix) holding linear program data is stored by column.

If false, the matrix is stored by row.

Definition at line 54 of file OSDataStructures.h.

int SparseMatrix::startSize

startSize is the dimension of the starts array

Definition at line 59 of file OSDataStructures.h.

int SparseMatrix::valueSize

valueSize is the dimension of the starts array

Definition at line 64 of file OSDataStructures.h.

int* SparseMatrix::starts

starts holds an integer array of start elements in coefMatrix (AMatrix), which points to the start of a column (row) of nonzero elements in coefMatrix (AMatrix).

Definition at line 70 of file OSDataStructures.h.

int* SparseMatrix::indexes

indexes holds an integer array of rowIdx (or colIdx) elements in coefMatrix (AMatrix).

If the matrix is stored by column (row), rowIdx (colIdx) is the array of row (column) indices.

Definition at line 76 of file OSDataStructures.h.

double* SparseMatrix::values

values holds a double array of value elements in coefMatrix (AMatrix), which contains nonzero elements.

Definition at line 82 of file OSDataStructures.h.
