I've been porting some IDL code over to scipy and ran into a problem with
The following would give me an error message running in a 32-bit environment
Traceback (most recent call last):
File "C:\Program Files (x86)\Wing IDE 4.0\src\debug\tserver\_sandbox.py",

vt = vt.transpose().astype(result_t)
The same function in 32-bit IDL seems to work fine (as well as in Matlab and
They both use the gesdd lapack function on the backend.
Why would the numpy routine have problems with this calculation when the
seemingly similar calculation works fine using IDL or Matlab?
