virtual bool GetSchurMatrix(const SmartPtr< const SchurData > &B, SmartPtr< Matrix > &S)
Function to extract a SchurMatrix corresponding to $B K^{-1} A$.
double Number
Type of all numbers.
Definition: IpTypes.hpp:17
PColumn(Index nrows, Number *values)
This class provides an easy interface for PCalculators with data where columns are not necessarily in...
EJournalLevel
Print Level Enum.
Index nrows_
Rows of P = Rows of KKT.
Template class for Smart Pointers.
Definition: IpSmartPtr.hpp:172
ReferencedObject class.
This class stores a list of user set options.
int Index
Type of all indices of vectors, matrices etc.
Definition: IpTypes.hpp:19
virtual bool InitializeImpl(const OptionsList &options, const std::string &prefix)
Overloaded from PCalculator.
Class responsible for all message output.
virtual bool ComputeP()
Function to start the computation of P from E_0 and KKT.
IndexPCalculator(SmartPtr< SensBacksolver > backsolver, SmartPtr< SchurData > A_data)
This class is the implementation of the PCalculator that corresponds to IndexSchurData.
EJournalCategory
Category Selection Enum.
