Member Function Documentation

virtual 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 Implements Ma27SolverBase.

virtual void Ma27Solver::getIndices (  int    irowM[], int    jcolM[] )  [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 Implements Ma27SolverBase.

virtual void Ma27Solver::solve (  OoqpVector &    rhs )  [virtual]

version of the main solve routine that takes argument as an OoqpVector Parameters: drhs  on input contains the right-hand side; on output contains the solution n  dimension of the system Implements Ma27SolverBase.
