    FFt in C and Passing a plane of 3-d array in C

    Hi, I am looking for C code to calculate the FFT (Fast Fourier Transform) of a 2-dimensional complex array.
    Also, how to pass a particular plane of a 3-dimensional array to a function in C.

    I would recommend "google" for the first one. The GNU scientific library might be a place to look too.

    As to the second, you can drop the last dimension only (not the first or the second).
