Hi, for those of you that are interested in signal processing and the like, I have added ⎕FFT which computes discrete Fourier transforms. ⎕FFT uses libfftw3, which needs to be installed before GNU APL is being ./configure'd. I also added a workspace gnuplot.apl which allows you to visualize some ⎕FFT results with the gnuplot program. Enjoy, /// Jürgen |
