%COMPILEDTTMEX Compile mex-functions for dtt1D, dtt2D, and dtt3D.
%
% DESCRIPTION:
%     compileDttMex compiles the mex functions for dtt1D, dtt2D, and dtt3D.
%
%     On Windows, the compilation uses a pre-compiled version of FFTW
%     included in the repository. If re-compiling, .lib files can be
%     generated from .dll files using a Visual Studio command prompt
%
%         lib /machine:x64 /def:libfftw3-3.def
%     
%     On Linux or macOS, fftw can be downloaded from http://www.fftw.org/.
%     Compile using the following options:
%
%         sudo ./configure --enable-avx CFLAGS="-m64 -fPIC"
%         sudo make
%         sudo make install
% 
%     Note, use --enable-sse2 if avx instructions aren't supported on
%     your processor.
%
%     It is assumed that a suitable C++ compiler is installed and selected
%     by calling mex -setup. See: https://www.mathworks.com/support/...
%     requirements/supported-compilers.html for more details. On linux,
%     specify the version of the compiler and FFTW to use in the code
%     below. On macOS, compiling mex files requires Xcode, which can be
%     downloaded from the app store.
