Check 1st Order Derivatives
Type : Integer
Range : {-1..:ref:Miscellaneous_Maxint }
Default : 0
This options controls how often the 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 initial point only. |
+n |
The derivatives are tested in all iterations that can be divided by n, provided the derivatives are computed in this iteration. (During phase 0, 1, and 3 derivatives are only computed when it appears to be necessary.) |
