+function out=fnn(varargin)
+%FNN Dimension estimation by false nearest neighbours.
+% Y=FNN(X) computes the vector Y of the amount of false
+% nearest neighbours (FNN) as a function of the embedding dimension.
+%
+% Y=FNN(X,M), where M is a scalar, computes the FNN up to dimension M.
+% The defeault is M=10.
+%
+% Y=FNN(X,M,R,S), where R and S are scalars, applies the neighbourhood
+% criterion R and the size of the neighbourhood S. The defeault is R=2
+% and S=Inf.
+%
+% Y=FNN(X,M,R,S,N), where N is a scalar, uses N random samples for
+% the determination of the FNNs. This speeds up the estimation,
+% especially for long data series. The defeault is N=length(X) if
+% the data length is smaller than 500, else N=200.
+%
+% FNN(...) without any output arguments opens a GUI for interactively
+% changing the parameters.
+%
+% By using the GUI, the FNNs can be stored into the
+% workspace.
+%
+% FNN(...,param) additional parameters according to the GUI are
+% available:
+% gui - Creates the GUI.
+% nogui - Suppresses the GUI.
+% silent - Suppresses all output.
+%
+% FNN without any arguments calls a demo (the same as the example
+% below).
+%
+% Examples: x = sin(0:.2:8*pi)' + .1*randn(126,1);
+% fnn(x,10,5)
+%
+% See also PHASESPACE, PSS, MI.
