Hi, I am implementing a Decimation in frequency algo using MATLAB. Can anbody give an efficient way of passing the twiddle factors to a 2 input 2 output butterfly. Thanks, Praveen

I heard that MATLAB has switched to the FFTW FFT which is very fast. If I remember correctly, other MATLAB-like programs, some free, also use FFTW. You may be blaming the slow FFT speed on the FFT algorithm instead of the built in lack of speed in MATLAB. Or you might be using an old version of MATLAB.
