    I want to use FFTW in C#, but I can not get it work. anyone knows it? there are lot of FFT implemented in C# but only supports with a data length of 2^n, anyone knows some good FFT algorithm supports arbitray length? thanks!!

        Take a look at ILNumerics[^] As long as you have the FFTW libraries in the same directory, all you need is the line

        ILMath.FFT = new ILFFTW3FFT();

        and ILNumerics will use FFTW. Dybs
