hello,i need to generate a generic program in matlab that gives me the numeric values of the real and imaginary parts of the twiddle factors used in FFT. I am designing an FFT processor and i need to store the values of these coefficients in a ROM. I am not very familiar with MATLAB and hence have been facing many problems with my design. Say for calculating a 256-point FFT, N%6; K=N-1; the twidle factor would then be=Cos(2*pi*k/N)-i*sin(2*pi*k/N)... for different values of k and N. I tried generating them ..but i could only plot the whole function ..i need to print the individual values of cos(2*pi*k/N) and sin(2*pi*k/N)..How can i do this? Any help would be grately appreciated. Many thanks, Pavan. |
