Decimation in Frequency FFT |
|
|
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 |

Better to avoid Matlab altogether then and use LabVIEW.

Isn't there already code for this?

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.
