Detailed Description

implements the linear solver class using the HSL MA27 solver

Constructor & Destructor Documentation

Ma27Solver::Ma27Solver ( )

inlineprotected

sets mMat to refer to the argument sgm

void Ma27Solver::copyMatrixElements	(	double	fact[],
		int	lfact
	)

virtual

copy the contents of the matrix into fact

Parameters

fact	on exit, contains the nonzero elements of the original matrix, stored as an array of doubles

virtual

change format for row/column index matrices, in preparation for call to MA27 FORTRAN routines

Parameters

irowM	array of nnz elements indicating row index (in range 1..n) of the corresponding matrix element
jcolM	array of nnz elements indicating col index (in range 1..n) of the corresponding matrix element

void Ma27Solver::solve ( OoqpVector & rhs )

virtual

version of the main solve routine that takes argument as an OoqpVector

Parameters
