How To Modify Field Data in the Merit Function Editor Using the FDMO operand

no@spam.com (Sanjay Gangadhara) — Thu, 21 Feb 2008 00:00:00 PST

Although only 12 field points can be defined in the Field dialog, the FMDO optimization operand allows these points to be re-defined on the fly during optimization. This means that any operand that uses a field number as an argument can be computed anywhere in the field of view. This article explains how to use this powerful capability.
