Initializes the solver for Jacobian calculations.
res = sjacobi_init(handle, n, m, x, fjac, eps)
res = djacobi_init(handle, n, m, x, fjac, eps)
The routine initializes the solver.
INTEGER. Length of F.
REAL for sjacobi_init
DOUBLE PRECISION for djacobi_init
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.
REAL for sjacobi_init
DOUBLE PRECISION for djacobi_init
Precision of the Jacobian matrix calculation.
REAL for sjacobi_init
DOUBLE PRECISION for djacobi_init
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.
Data object of the INTEGER*8. 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.
INTEGER. 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.fi include file.
