Yorick Plugins and Tips

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

Download

The last version of YNFFT is here.

Installation

1. Make sure you have installed the NFFT library (http://www-user.tu-chemnitz.de/~potts/nfft/), the FFTW library (http://www.fftw.org/) and Yorick (http://yorick.github.com/).
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$(PREFIX)/lib -lnfft3 -lfftw3
   PKG_CFLAGS=-I$(PREFIX)/include
   PKG_LDFLAGS=
   

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
