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. | |
SymScaledMatrix () | |
Default Constructor. | |
SymScaledMatrix (const SymScaledMatrix &) | |
Copy Constructor. | |
void | operator= (const SymScaledMatrix &) |
Overloaded Equals Operator. | |
Private Attributes | |
SmartPtr< const SymMatrix > | matrix_ |
const version of the unscaled matrix | |
SmartPtr< SymMatrix > | nonconst_matrix_ |
non-const version of the unscaled matrix | |
SmartPtr< const SymScaledMatrixSpace > | owner_space_ |
Matrix space stored as a SymScaledMatrixSpace. |
Class for a Matrix in conjunction with its scaling factors for row and column scaling.
Operations on the matrix are performed using the scaled matrix. You can pull out the pointer to the unscaled matrix for unscaled calculations.

virtual bool Ipopt::SymScaledMatrix::HasValidNumbersImpl | ( | ) | const [protected, virtual] |
Method for determining if all stored numbers are valid (i.e., no Inf or Nan).
It is assumed here that the scaling factors are always valid numbers.
