Problem with Chebyshev basis?

See original GitHub issue

Hi Mikael,

I have started to implement my Rayleigh-Benard solver and wanted to play a bit with the Poisson and Biharmonic solvers first. To do so, I downloaded the scripts available in the demo folder and I have some weird things going on:

For both the Poisson and Biharmonic scipts (2D ones), if I set the basis used in the non-homogeneous direction to be Chebyshev, the right-hand-side vector f_hat = inner(v, fj, output_array=f_hat) all its entries turn out be to equal to 0 + 0j.
If instead I set the basis to be Legendre polynomials, then everything works out correctly.

For information, I have installed shenfun using conda.

Awesome! It now works like a charm. Thanks a lot.

I will get back to you whenever I am done with my 2D Rayleigh-Benard solver. Once it works (and has been validated), I can eventually send a pull request to add it to the demos if you want.

Should be ready now. Build version 7. Just realised, though, that python=2.7 version has not been uploaded to Anaconda cloud for linux after the move to Circle-Ci 2.0 some months ago.
