fix to RBFard derivative #29

Closed alexfeld closed 8 years ago

Fixed a bug in the RBFard derivative calculation that prevented the optimization from working. Also modified the default usage of minimize (through the opt class) in order to make the optimization a bit more robust (at least that was my experience).
