[matplotlib-devel] Interpolation in a triangular mesh (tri.Triangulation)

2012-10-28 Thread GBillotey 
   Hi!


I had recently to develop interpolators for a function defined at the nodes
of a user-specified triangular mesh.
(Beside interpolation, it can help producing higher-quality tricontour
plots, using interpolation on a refined mesh and matplotlib tricontour
function.)

Being a regular user of matplotlib, I would be happy if it can be useful to
others...
The code is hosted here:
https://github.com/GBillotey/trimesh-interpolator.git


Please let me know if it this dev. can be useful and if the code needs some
cleaning (I am not a computer scientist, only a mechanical engineer)


Cheers,
Geoffroy.

[matplotlib-devel] Test Failure: AttributeError: incompatible shape for a non-contiguous array

2012-10-28 Thread Patrick Marsh 
Greetings,

I've banged my head against this problem for 2 days and have given up on
figuring it out on my own…

After updating numpy and matplotlib to the latest versions from github
Saturday morning, I keep getting "AttributeError: incompatible shape for a
non-contiguous array" errors all over the place when plotting. When I run
tests on numpy, everything passes. When I run tests on matplotlib, I get 51
errors, with a vast majority of them (possibly all) being the
non-contiguous array errors. (Sample below)

Any suggestions here? I'm totally stumped.
