nag_opt_check_deriv (e04hcc) Example Program Results

The test point is:
   1.4600  -0.8200   0.5700   1.2100

First derivatives are consistent with function values.

At the test point, objfun gives the function value    6.2273e+01
and the 1st derivatives

    -1.285e+01     -1.649e+02      5.384e+01      5.775e+00
