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. | |
DiagMatrix () | |
Default Constructor. | |
DiagMatrix (const DiagMatrix &) | |
Copy Constructor. | |
void | operator= (const DiagMatrix &) |
Overloaded Equals Operator. | |
Private Attributes | |

virtual bool Ipopt::DiagMatrix::HasValidNumbersImpl | ( | ) | const [protected, virtual] |
Method for determining if all stored numbers are valid (i.e., no Inf or Nan).
Reimplemented from Ipopt::Matrix.
virtual void Ipopt::DiagMatrix::ComputeRowAMaxImpl | ( | Vector & | rows_norms, |
