Prototype several fast solvers for Poisson's equation. First stage: 2d region, rectangular region, boundary conditions of the first type.
Needed: FFT (e.g. https://epubs.siam.org/doi/abs/10.1137/1019071) Cyclic reduction (as above) FFT+domain decomposition ( http://num-meth.srcc.msu.ru/zhurnal/tom_2015/pdf/v16r110.pdf )
FFT and Cyclic reduction are in progress;
