    Question fourier transform in C

    hi.
    as part of my project at uni, i need to perform a fourier transform on an array of real data points. these are in y[]. the trouble is i don't really know where to start

    does anyone know if there are any pre-made functions included in the include files or know anyway of doing this.

    (im using Salford Plato v2.21)

    thanks,
    blinky

    Yours is a common problem. If you search the web you'll find plenty of implementations in C.

    If you're refering to www.fftw.org then you'll have to compile the fftw-library. Just follow the instructions in the manual .
