Fast SFT - Spatial Fourier Transform, S/T/C (CORE)
The externals (cores) are the heart of SOFiA. Precompiled cores for MATLAB 64 Bit on MAC-OS, MATLAB 32 and 64 Bits on Windows and MATLAB 32 Bit on Linux are included in the package. (Thanx to Julian Strobl for compiling the cores on Linux 32 Bit!) The cores involve Legendre polynomials/spherical harmonics and Bessel/Hankel functions provided by the peer-reviewed BOOST C++ Math Library under the BOOST Software License.
