Add sinc grid #3

Closed tberlok closed 6 years ago

tberlok commented 6 years ago

It might be interesting to add the sinc grid.

According to Boyd, boundary conditions that the variables goes to zero at \pm \infty is automatically satisfied when using the sinc grid. This has the advantage that the evp is a standard evp, not a generalized evp.

See Appendix F.7 in Boyd.
