Intel® oneAPI Math Kernel Library Developer Reference - C

Routines for the Cartesian Solver

The section describes Poisson Solver routines for the Cartesian case, their syntax, parameters, and return values. All flavors of the same routine are described together: single- and double-precision and 2D and 3D.

Note

Some of the routine parameters are used only in the 3D Fast Helmholtz Solver.

Poisson Solver routines call Intel® oneAPI Math Kernel Library FFT routines (described inFFT Functions), which enhance performance of the Poisson Solver routines.
