Several aspects of the Intel® oneAPI Math Kernel Library (oneMKL) Poisson Solver interface are platform-specific and language-specific. To promote portability of the Intel® oneAPI Math Kernel Library (oneMKL) Poisson Solver interface across platforms and ease of use across different languages, Intel® oneAPI Math Kernel Library (oneMKL) provides you with the Poisson Solver language-specific header file to include in your code:
The header file defines the function prototypes for the Cartesian and spherical solver available in specific function descriptions.
