NAG_CHECK_DERIV

 
Checks that a user-supplied C function for evaluating a vector of functions and
the matrix of their first derivatives produces derivative values which are
consistent with the function values calculated.
 
Classes  :  F2 . Solution of a system of nonlinear equations
 
Type     : C subroutine in NAGC library (C05 sublibrary).
Access   : Proprietary. Many implementations available.
Precision: Double.
Note     : This procedure may also be invoked using the name c05zbc.
 
Usage    : void nag_check_deriv(Integer n, double x[], double fvec[], double
           fjac[], Integer tdfjac, void (*f)(Integer n, double x[],double
           fvec[], double fjac[], Integer tdfjac, Integer *userflag),
           NagError *fail)
