?jacobi_init
Initializes the solver for Jacobian calculations.
Syntax
MKL_INT sjacobi_init (_JACOBIMATRIX_HANDLE_t* handle, const MKL_INT* n, const MKL_INT* m, const float* x, const float* fjac, const float* eps);
MKL_INT djacobi_init (_JACOBIMATRIX_HANDLE_t* handle, const MKL_INT* n, const MKL_INT* m, const double* x, const double* fjac, const double* eps);
Include Files
- mkl.h
Description
The routine initializes the solver.
Input Parameters
- n
- Length of x.
- m
-
Length of F.
- x
-
Array of size n. Vector, at which the function is evaluated.
A reference to this array is stored in handle for later use and modification by ?jacobi_solve.
- eps
-
Precision of the Jacobian matrix calculation.
- fjac
-
Array of size m by n. Contains the Jacobian matrix of the function.
A reference to this array is stored in handle for later use and modification by ?jacobi_solve.
Output Parameters
- handle
-
Data object of the _JACOBIMATRIX_HANDLE_t type. Stores internal data, including pointers to the user-provided arrays x and fjac. It is important that the user does not move or deallocate these arrays until after calling the ?jacobi_delete routine.
- res
-
Indicates task completion status.
res = TR_SUCCESS - the routine completed the task normally.
res = TR_INVALID_OPTION - there was an error in the input parameters.
res = TR_OUT_OF_MEMORY - there was a memory error.
TR_SUCCESS, TR_INVALID_OPTION, and TR_OUT_OF_MEMORY are defined in the mkl_rci.h include file.
