wavevib

  WAVEVIB generates a vibroseis waveform (Clauder wavelet) by ％ first calling SWEEP to generate a linear sweep and then calling ％ AUTO to autocorrelate that sweep. Theoretically, the autocorrelation ％ length is ~ 2*slength but only only the central wlength long ％ part is generated. This is like windowing the auto with a boxcar.(WAVEVIB generates a vibroseis waveform (Clauder wavelet) by first calling SWEEP to generate a linear sweep and then calling AUTO to autocorrelate that sweep.
