Here's a use for sympy that I thought might be interesting to the list. Sympy computes derivatives that are then used in generated python code.
The code generation code is located here https://quameon.svn.sourceforge.net/svnroot/quameon/trunk/codegen/ In particular, lang_py.py defines nodes for a python syntax tree, and sympy_to_py.py converts a sympy expression to this syntax tree. The actual problem-specific code is here: https://quameon.svn.sourceforge.net/svnroot/quameon/trunk/codegen/primitive_gaussian/deriv.py It defines some functions used in quantum chemistry and computes the first and second derivatives. The output can be seen here https://quameon.svn.sourceforge.net/svnroot/quameon/trunk/quameon/orbital/atomic_gto_primitive.py Mark --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
