[wz Xz] = zoom_dft(Xw,wc,dw) allows zooming in on the Fourier Transform in the region wc-dw to wc+dw

File Information
Description	This function returns N point DFT samples of 2dw band of Fourier transform of a sequence. Typically, fft() returns N samples of Fourier transform ranging from 0 to 2pi. This function takes the N-point DFT samples and returns N-point samples corresponding to frequency band wc-dw to wc+dw.
MATLAB release	MATLAB 7.7 (R2008b)
