?jacobi_solve
Computes the Jacobian matrix of the function using RCI and the central difference algorithm.
Syntax
res = sjacobi_solve(handle, f1, f2, RCI_Request)
res = djacobi_solve(handle, f1, f2, RCI_Request)
Include Files
- Fortran: mkl_rci.fi, mkl_rci.f90
Description
The ?jacobi_solve routine computes the Jacobian matrix of the function using RCI and the central difference algorothm.
See usage examples in the examples\solverf\source folderof your Intel® oneAPI Math Kernel Library (oneMKL) directory. Specifically, see sjacobi_rci_f.f and djacobi_rci_f.f.
Input Parameters
handle |
Type INTEGER*8. |
RCI_Request |
INTEGER. Set to 0 before the first call to ?jacobi_solve. |
Output Parameters
f1 |
REAL for sjacobi_solve DOUBLE PRECISION for djacobi_solve Contains the updated function values at x + eps. |
f2 |
REAL for sjacobi_solve DOUBLE PRECISION for djacobi_solve Array of size m. Contains the updated function values at x - eps. |
RCI_Request |
Provides information about the task completion. When equal to 0, the task has completed successfully. RCI_Request= 1 indicates that you should compute the function values at the current x point and put the results into f1. RCI_Request= 2 indicates that you should compute the function values at the current x point and put the results into f2. |
res |
INTEGER. Indicates the task completion status.
TR_SUCCESS and TR_INVALID_OPTION are defined in the mkl_rci.fi include file. |
