Ambiguity function

DESCRIPTION ^

 Ambiguity function

 Computes the ambiguity function of the input signal. An analytic
 signal generator is called if the input signal is real. This version
 takes advantage of the property K(n,-m)=K*(n,m) to increase
 calculation speed.

 Usage: 

     af = ambf( signal, lag_res, window_length )


 Parameters:

     af

      The computed ambiguity function representation. size(af) will
      return [a, b], where b is the next largest power of two above
      (2*window_length), and a is equal signal length.

    signal

      Input one dimensional signal to be analysed. An analytic signal
      is required for this function, however, if signal is real, a
      default analytic transformer routine will be called from this
      function before computing the ambiguity function.

    window_length

      The number of signal samples used for analysis.

    lag_res

      The number of lag to skip between successive slices of
      the analysis.
