Syntax
dcgmrhs_get(n, x, b, RCI_request, ipar, dpar, tmp, itercount)
Include Files
The Fortran interface is specified in the mkl_rci.fi include file and the C interface is specified in the mkl_rci.h include file.
Description
The routine dcgmrhs_get retrieves the current iteration number of the solving process.
Note
To use this routine with the name dcg_get, switch on the compiler preprocessor and include the files mkl_solver.h for C/C++, or mkl_solver.f77 for FORTRAN.
Input Parameters
- n
INTEGER. Contains the size of the problem, and the sizes of arrays x and b.
- x
DOUBLE PRECISION matrix of size n-by-nrhs. Contains the initial approximation to the solution vectors.
- nrhs
INTEGER. This parameter sets the number of right-hand sides.
- b
DOUBLE PRECISION matrix of size (nrhs,n). Contains the right-hand side .
- RCI_request
INTEGER. This parameter is not used.
- ipar
INTEGER array of size (128+2*nrhs). Refer to the CG Common Parameters.
- dpar
DOUBLE PRECISION array of size (128+2*nrhs). Refer to the CG Common Parameters.
- tmp
DOUBLE PRECISION array of size (n, 3+nrhs). Refer to the CG Common Parameters.
Output Parameters
- itercount
INTEGER argument. Contains the value of the current iteration number.
Return Values
The routine dcgmrhs_get does not return any value.
