signal if auto-AF, or [X1,X2] if cross-AF (length(X)=Nx).
vector of lag values (default is -Nx/2:Nx/2).
number of frequency bins (default is length(X)).
if 1, (default is 0) the progression of the algorithm is shown.
if input contains the string 'plot', the output values will be plotted
doppler-lag representation, with the doppler bins stored in the rows and the time-lags stored in the columns. When called without output arguments, AMBIFUNB displays the squared modulus of the ambiguity function by means of contour.
vector of doppler values.
ambifunb computes the narrow-band ambiguity function of a signal X, or the cross-ambiguity function between two signals.
