mlfGmres

Generalized Minimum Residual method (with restarts)

Minimum number of arguments: twelve, maximum: user-defined. Terminate the argument list with a NULL.

C Prototype

mxArray *mlfGmres(mxArray **flag, mxArray **relres, mxArray **iter,
                  mxArray **resvec, mxArray *A, mxArray *b,
                  mxArray *restart, mxArray *tol, mxArray *maxit,
                  mxArray *M1, mxArray *M2, mxArray *x0,...);

C Syntax

#include "matlab.h"

mxArray *A, *b, *restart;       /* Required input argument(s) */
mxArray *tol, *maxit;           /* Optional input argument(s) */
mxArray *M, *M1, M2, x0;        /* Optional input argument(s) */
mxArray *flag=NULL,*relres=NULL;/* Optional output argument(s) */
mxArray *iter=NULL,*resvec=NULL;/* Optional output argument(s) */
mxArray *x = NULL;              /* Return value */

                      A,b,restart,NULL,NULL,NULL,NULL,NULL,NULL));

                      A,b,restart,tol,maxit,NULL,NULL,NULL,NULL));
