Routines for the Spherical Solver

The section describes Poisson Solver routines for the spherical case, their syntax, parameters, and return values. All flavors of the same routine are described together: single- and double-precision and periodic (having names ending in "p") and non-periodic (having names ending in "np").

These Poisson Solver routines also call the Intel MKL FFT routines (described in FFT Functions), which enhance the performance of the Poisson Solver routines.
