Hi all, I would like to inform you about new packages - FuncDesigner and DerApproximator. They have been extracted from OpenOpt into standalone Python modules.
FuncDesigner is a convenient tool for building functions and getting their derivatives via Automatic differentiation (http://openopt.org/ AD), not to be confused with numerical differentiation via finite- differences derivatives approximation and symbolic differentiation provided by Maxima, SymPy etc. See http://openopt.org/FuncDesigner for more details DerApproximator is a small yet important package for getting/checking derivatives (currently only 1st ones), extracted from OpenOpt framework to be standalone Python module. It is required by FuncDesigner (for obtaining derivatives of oofuns beyond standard set without routines to yield them directly) and some OpenOpt solvers (when there are some functions without user-supplied derivatives). See http://openopt.org/DerApproximator for more details. All my tests pass OK, but since there was an awful lots of changes, I decided it's better to introduce RCs before stable releases, mb some bugs are still lurking.
