bDeleteArrays is true if we delete the arrays in garbage collection set to true by default | |
bool | isColumnMajor |
isColumnMajor holds whether the coefMatrix (AMatrix) holding linear program data is stored by column. | |
int | startSize |
startSize is the dimension of the starts array | |
int | valueSize |
valueSize is the dimension of the starts array | |
int * | 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). | |
int * | indexes |
indexes holds an integer array of rowIdx (or colIdx) elements in coefMatrix (AMatrix). | |
double * | values |
values holds a double array of value elements in coefMatrix (AMatrix), which contains nonzero elements. |

Constructor.
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. |

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 185 of file OSGeneral.h.
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.
