Member Function Documentation

virtual int LinSysCore_flexible::resetConstraints ( double  s )

pure virtual

Reset any previously-loaded lagrange multiplier constraint-relations.

Referenced by LinSysCoreFilter::deleteMultCRs().

virtual int LinSysCore_flexible::setMultCRComplete ( )

pure virtual

Signal that we're done calling the setMultCREqns function.

Referenced by LinSysCoreFilter::setLinSysCoreCREqns().

virtual int LinSysCore_flexible::constraintsLoadComplete ( )

pure virtual

Supply LinSysCore_flexible with information defining the structure of the constraint section of the global matrix. This function is similar to the LinearSystemCore::setMatrixStructure function, except that only the constraint section of the matrix is supplied, AND only the "row" portion. i.e., the structure of C is supplied, but not C^T. Note also, that only the local rows of the C matrix are supplied.

Parameters

numLocalRows	Number of local rows in C.
globalRowNumbers	Specifies whichrows in the global system matrix are occupied by the constraint matrix C, but only those rows which are locally stored.
rowLengths	List of length numLocalRows. Specifies how many column-entries are in each row of the constraint matrix C.
globalColIndices	Table containing the column-indices in C. This "table" has number-of-rows = numRows, and row i is of length rowLengths[i].

Returns

error-code 0 if successfulSignal the underlying solver library that the loading of constraints is now complete. (Constraint-loading functions are in LinearSystemCore.) Important Note: This method, LinSysCore_flexible::constraintsLoadComplete() will be called INSTEAD OF LinearSystemCore::matrixLoadComplete().
