[SciPy-user] Bugs in special

[Eli Brosh]

Hello
I am trying to convert from MATLAB to Python with SciPy.
I am using Python 2.4.3 for Windows (Enthought Edition)
As a start, I tried to use the special functions from the SciPy  "special" module.
There, I encountered some problems that may be a result of bugs in SciPy.
 
 
The session (in IDLE) goes like:
 
>>>from scipy import *
>>> x=.5
>>> special.jv(0,x)
0.938469807241
>>> y=.5+1.j
>>> y
(0.5+1j)
>>> special.jv(0,y)
>>> ================================ RESTART ================================

When I try to put a complex argument in special.jv, I get an error message from the operating system (windows XP):
It says "pythonw.exe has encountered a problem and needs to close. We are sorry for the inconvenience."
 
The IDLE does not close but it is restarted:
There appears a line: 
>>> ================================ RESTART ================================
 
This does not occur when the argument of special.jv is real.
 
However, even real arguments in special.ber and special.ker provoked the same crash and the same error message.
 

 
Is this a bug in SciPy or am I doing something wrong ?
 
 
Thanks
Eli
