[SciPy-User] convolution of 2d arrays of exotic complex numbers (dual and split)

i used scipy.signal.convolve to work with complex-number arrays.
now i need to convolve arrays of dual numbers (i*i=0) and split-complex
numbers (i*i=1). so i have a class (
http://dl.dropbox.com/u/4988243/iComplex.py) which implements this numbers:
class PlainComplex(Complex):
def __mul__(self, other):
other = ToComplex(other)
return PlainComplex(self.re*other.re - self.im*other.im,
self.im*other.re + self.re*other.im)
class DualComplex(Complex):
def __mul__(self, other):
other = ToComplex(other)
return DualComplex(self.re*other.re,
self.im*other.re + self.re*other.im)
class SplitComplex(Complex):
def __mul__(self, other):
other = ToComplex(other)
return SplitComplex(self.re*other.re + self.im*other.im,
self.im*other.re + self.re*other.im)
as you can see only multiplication function is being changed.
the question: is it possible to feed arrays of such objects to scipy's
convolution function? when i try to do it for PlainComplex class it seems
to work wrong (different from using python's complex numbers):
http://dl.dropbox.com/u/4988243/sandbox.py - my complex
http://dl.dropbox.com/u/4988243/sandbox2.py - python complex
or maybe there is some alternative solution?
thanx!
