Private Member Functions | |
Default Compiler Generated Methods | |
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called. | |
| ScaledMatrix () | |
| Default Constructor. | |
| ScaledMatrix (const ScaledMatrix &) | |
| Copy Constructor. | |
| void | operator= (const ScaledMatrix &) |
| Overloaded Equals Operator. | |
Private Attributes | |
| SmartPtr< const Matrix > | matrix_ |
| const version of the unscaled matrix | |
| SmartPtr< Matrix > | nonconst_matrix_ |
| non-const version of the unscaled matrix | |
| SmartPtr< const ScaledMatrixSpace > | owner_space_ |
| Matrix space stored as a ScaledMatrixSpace. | |
Operations on the matrix are performed using the scaled matrix. You can pull out the pointer to the unscaled matrix for unscaled calculations.
