[Numpy-discussion] how do I delete unused matrix to save the memory?

I have the same problem.  I tried the del command below, but foundon that it
removes the names of the ndarrays from memory, but does not free up the
memory on my XP system (python 2.5.2, numpy 1.2.1).  Regular python objects
release their memory when I use the del command, but it looks like the
ndarray objects do not.
