[PYTHON MATRIX-SIG] New release of NumericPython 0.31

[Hinsen Konrad]

   >From the tutorial:
   1)  First problem is with the types.py file. For some reason when it's imported
   vars(__builtins__) is an illegal argument while it works fine from the prompt.

You can solve this temporarily by removing the call to vars().  It
seems that inside a module definition, __builtins__ is not a module,
but a dictionary. I suspect this is a bug in Python, until someone
can explain me the reason...

   2) The following basic function is worrisome as well...

   >>> m = Matrix([[1,2,3], [4,5,6], [7,8,9]])
   >>> m*m
   Traceback (innermost last):
     File "<stdin>", line 1, in ?
     File "/local2/tools/lib/python/numeric/Matrix.py", line 74, in __mul__
   NameError: MathError
   >>> 

When I try this here, it is a bit different:

Traceback (innermost last):
  File "test.py", line 3, in ?
    m*m
  File "/usr/people/hinsenk/lib/python/numeric/Matrix.py", line 5, in __mul__
    return self.__return_constructor__(self.array.matrixMultiply(other))
AttributeError: __int__

This indicates that some function can't deal with an int matrix.
What puzzles me in your error message is the indication "line 74".
Matrix.py is rather short!
