fft_freq_axis.m

Frequency axis for FFT with optional zero-filling.

Syntax

          [f_shift,f,df,nfft]=fft_freq_axis(npts,dt,zf)

Parameters

       npts    - number of acquired time-domain points
       dt      - time step between points
       zf      - zero-fill length added to time domain

Outputs

       f_shift - frequency axis for fftshift(fft(...))
       f       - frequency axis for fft(...)
       df      - frequency resolution
