New issue 2801 by matt...@gmail.com: lambdify() is not mentioned anywhere
http://code.google.com/p/sympy/issues/detail?id=2801
lambdify() is one of most important functions in SymPy (for
interoperability with numerical libraries the most important). However it's
not mentioned anywhere, although it has a good docstring. The result of
`git grep` stands for itself:
$ git grep lambdify doc/
doc/src/aboutus.txt:#. Sebastian Krämer: implemented lambdify/numpy/mpmath
cooperation, bug fixes, refactoring, lambdifying of matrices, large
printing refactoring and bugfixes
doc/src/aboutus.txt:#. Andrew Straw: lambdify() improvements
doc/src/aboutus.txt:#. Matthew Brett: fixes to lambdify
doc/src/modules/physics/mechanics/examples.txt:maximum recursion depth
being exceeded; I also tried lambdifying this, and it
lambdify's docstring must be pulled into docs (there is already a generic
issue for this), but we also need a good tutorial showing users how to
cooperate with NumPy, SciPy etc. This issue (not the only one by the way)
was pointed out to me by Fernando Perez during my stay at Berkeley this
week, when trying to solve a practical symbolic-numeric problem. SymPy has
already *a lot* of features, but unfortunately most of them are deeply
buried in the internals of SymPy and known only to its developers. Also we
have to check what does ufuncify() do, because it was reported to me that
it's extremely slow.
