What is PyQwt3D ( http://pyqwt3d.sourceforge.net) ?
- it is a set of Python bindings for the QwtPlot3D C++ class library
which extends the Qt framework with widgets for 3D data visualization.
PyQwt3D inherits the snappy feel from QwtPlot3D.

Using numpy-1.0.2/python-2.5/winxp pro sp2: in the following, the only
array is 'a', and I'm not using it as an index, so why do I get the
IndexError below?
--- start python session ---
>>> a=array([[1,3],[2,4]])
>>> a
array([[1, 3],
[2, 4]])
>>> f=lambda i,j: a[i,j]
>>> f(1,1)

By the way, you can get all the frequencies pretty fast
using a defaultdict:

You can try using hist() with the correct range and number of bins.

Hi all,
I have a list of integer numbers. The entries can vary between 0 and 19.
How can I count the occurrence of any number. Consider
>>> data
[9, 6, 9, 6, 7, 9, 9, 10, 7, 9, 9, 6, 7, 9, 8, 8, 11, 9, 6, 7, 10, 9, 7, 9, 7,
8, 9, 8, 7, 9]
Is there a better way than using, e.g.
>>> shape(wher
Thank you for your comments!
I will try this fftw3-scipy approach and see how much faster I can get.
Maybe this is enough for me...?
