I'm announcing the availability of Version 1.2 of the Cephes module at http://oliphant.netpedia.net Cephes module provides many special functions of physics to the Numerical Python user as ufuncs which are generalized functions that automatically map over array arguments and follow useful broadcasting rules. I would like to see more special functions added to the library even if they are written in Python. Towards that end, version 1.2 contains a new python wrapper module called SpecialFuncs.py that can include Python-only special functions. In addition, I have added a method to cephesmodule called arraymap that acts like the map function but performs the broadcasting rules of ufuncs and returns Numerical Python arrays as output. I have also included a class that allows wrapping a Python function that takes scalar inputs and returns scalar outputs and returns a ufunc-like function which automatically maps over array input arguments following the ufunc broadcasting rules to return appropriately-sized outputs. So, if you can't figure out how to "vectorize" your function. You can wrap it in this class and get mapping behavior automatically. The looping is all written in C and so is reasonably fast. Comments and contributions are welcome.
