function xout=jrqa(varargin)
%JRQA Computes and plots the JRQA measures.
% Y=JRQA(X [,Y] [,param1,param2,...])
% Recurrence quantification analysis of the joint recurrence
% plot of the vectors X and Y.
%
% The input vectors can be multi-column vectors, where
% each column will be used as a component of the
% phase-space vector. However, if the first column is
% monotonically increasing, it will be used as an
% time scale for plotting.
%
% Y=JRQA(X,M,T,E,W,WS,LMIN,VMIN,TW) computes the
% recurrence quantification analysis of the recurrence
% plot of X by using the dimension M, delay T, the
% size of neighbourhood E, the window size W and
% a window shifting value of WS. LMIN and VMIN
% specify the minimal length of diagonal and vertical
% line structures (default is 2) and TW specifies the
% Theiler window (default is 1).
%
% JRQA(...) without any output arguments opens a
% GUI for interactively control the JRQA. If an
% output is specified with using the option 'gui',
% then the output will contain the figure handle.
%
% Parameters:
% Dimension M, delay T, the size of
% neighbourhood E, the window size W and the shift
% value WS are the first five numbers after the data
% series; if W is empty, the whole plot will be calculated.
% The next two optional numeric parameters LMIN and VMIN
% specify the minimal length of line structures.
%
% As the last numeric parameter, the size of the Theiler
% window TW can be specified (default is 1). This window
% excludes the recurrence points parallel to the main
% diagonal from the analysis. The application of the
% Theiler window is useful only for recurrence plots. In
% joint recurrence plots, the size of the Theiler window will
% be set automatically to zero.
%
% Further parameters can be used to switch between various
% methods of finding the neighbours of the phasespace
% trajectory, to suppress the normalization of the data
% and to suppress the GUI (useful in order to use this
% programme by other programmes). The minimal length of
% diagonal and vertical structures can be setted only in
% the GUI.
%
% Methods of finding the neighbours.
% maxnorm - Maximum norm.
% euclidean - Euclidean norm.
% minnorm - Minimum norm.
% nrmnorm - Euclidean norm between normalized vectors
% (all vectors have the length one).
% fan - Fixed amount of nearest neighbours.
% inter - Interdependent neighbours.
% omatrix - Order matrix.
% opattern - Order patterns recurrence plot.
%
% Normalization of the data series.
% normalize - Normalization of the data.
% nonormalize - No normalization of the data.
%
% Suppressing the GUI.
% gui - Creates the GUI.
% nogui - Suppresses the GUI.
% silent - Suppresses all output.
%
% Parameters not needed to be specified.
%
% The window of length w is applied on the data and not on the RP,
% i.e. the RP will have smaller size than the window, thus w-(m-1)*tau.
% If we consider the data window at time i ... i+w, the corresponding RQA
% measures are assigned to time i. Therefore, if you see a beginning
% of a transition in the plot of the RQA measures at time i, this
% transition will probably happen at time i+w-(m-1)*tau.

% Y(:, 2) = DET (determinism)
% Y(:, 3) = <L> (mean diagonal line length)

% Y(:, 6) = LAM (laminarity)
% Y(:, 7) = TT (trapping time)
% Y(:, 8) = Vmax (maximal vertical line length)

% Examples: N = 500; w = 40; ws = 10;
% b = .4; a = .6; mu = .8:-0.7/N:.1;
% % two mutually coupled logistic maps
% for i = 2:N,
% a(i) = 3.6 * a(i-1) * (1 - a(i-1));
% b(i) = 4 * b(i-1) * (1 - b(i-1)) - mu(i)*a(i);
% end
