Check 2nd Order Derivatives

Type : Integer

Range : {-1..:ref:Miscellaneous_Maxint }

Default : 0

This options controls how often the second order derivatives are tested. Debugging of derivatives is normally only relevant for user-written functions in external equations. Possible values are:

0	No debugging.
-1	The derivatives are tested in the first point in which second derivatives are used only.
+n	The derivatives are tested every n-th call.
