Thanks for the hint. I thought about Cython myself but I was unable to
get even the slightest speed gain out of it.
Here is the equivalent Cython code with the timing and setup.py. I typed
(I think). Am I missing something obvious?
Cheers

Yes I did. Slicing and Cython do not mix too well. Using an explicit
loop fixes the problem. In case anybody is interested the code is attached.
Thanks for your help

Boiled it down a bit more to only include code that actually takes time.
First time around I found the other variant more instructive because it
shows the discrepancy between the DCT and the loop but might be
confusing.
I didn't look into that but it definitely sounds interesting. Especially
as the coefficient manipulation is mildly unstable for higher
derivatives. Need to work out the math first though ;). Thanks for the hint.

Hi all,
I have a 3D orthogonal and non-uniform grid representing a scalar field. I'm
using matplotlib.image.NonUniformImage() to plot it similarly to imshow().
What I'd like to do is plot the values of the scalar field across a specific
line (say, from point A to B).
Any suggestion?
Thanks!
