Download and make

1. Install the FFTW library (version 3), available from www.fftw.org. Generally this will mean
   > ./configure -prefix <FFTW_PATH>
   > make
   > make install
2. Download from www.math.uni-luebeck.de/potts/nfft
   > tar xfv nfft2.tar will create a directory ./nfft2
   ./nfft2> ./configure <FFTW_PATH> creates all makefiles
   ./nfft2> make creates the library and all examples

The following options are determined at compile time, realised in the Makefiles and in the file ./include/options.h, respectively.
