Never just say "I got an error." It tells us nothing. Copy-and-paste the exact
error message. I presume, however,

hmm
is numpy really efficient for 3x3 (or 4x4) matrices and vectors?
IMHO an optimized matrix4x4 class can be much faster (i'm just guessing
here)
eg cgtypes is a simple c++ implementation with boost-python wrapper:

I will just jump in an use NumPy. I hope this one will stick and evolve
into the mother of array packages.
How stable is it ? For now I really just need basic linear algebra.
i.e. matrix multiplication, dot, cross etc

Ok, I will look at NumPy ...
I have another question about performance. Are the array operations
such as matrix multiplication implemented in
python or in C ? I was under the impression that the function calls in
numarray are only wrappers to C code, but now I suspect that matrix
multiplicaiton is
