Yorick Plugins and Tips

YNFFT is a Yorick plugin for NFFT (nonequispaced fast Fourier transform).


The last version of YNFFT is here.


  1. Make sure you have installed the NFFT library (, the FFTW library ( and Yorick (
  2. Go to the YNFFT directory:
    cd $DIR/ynfft-$VERSION
  3. Edit the file "Makefile" and check the values of the variables PKG_DEPLIBS, PKG_CFLAGS and PKG_LDFLAGS; for instance, assuming PREFIXis a variable with the top directory where FFTW and NFFT libraries are installed:
    PKG_DEPLIBS=-L$(PREFIX)/lib -lnfft3 -lfftw3
  4. Update the paths in the file "Makefile" for compilation by executing the following command:
    yorick -batch make.i
    where "yorick" can be replaced by the full path to your Yorick interpreter if not installed in a standard location.
  5. Optionally, check the plugin:
    make tests
    You may have to set some environment variable for the dynamic loader (LD_LIBRARY_PATHon Linux) if the NFFT library is installed in a non-standard location, e.g.:
    LD_LIBRARY_PATH=$PREFIX/lib make tests
  6. Finally, install the plugin:
    make install
