%CRQA Computes and plots the CRQA measures.
% Y=CRQA(X [,Y] [,param1,param2,...])
% Recurrence quantification analysis of the cross 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=CRQA(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).
%
% CRQA(...) without any output arguments opens a
% GUI for interactively control the CRQA. 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
% cross 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.
%
% Output:
% Y(:,1)=RR (recurrence rate)
% Y(:,2)=DET (determinism)
% Y(:,3)=<L> (mean diagonal line length)
% Y(:,4)=Lmax (maximal diagonal line length)
% Y(:,5)=ENTR (entropy of the diagonal line lengths)
% Y(:,6)=LAM (laminarity)
% Y(:,7)=TT (trapping time)
% Y(:,8)=Vmax (maximal vertical line length)
% Y(:,9)=T1 (recurrence time of 1st type)
% Y(:,10)=T2 (recurrence time of 2nd type)
%
% Warning:
% The RQA measures may differ from those of the RQA programmes by
% Charles Webber Jr. For compatibility use a Theiler window of
% size one and ensure that the data are normalized before by the
% same distance which is used in the RQA programmes; e.g. normalize
% with the maximal phase space diameter, which can be estimated
% with the programme PSS:
%
% RQA=crqa(100*x/pss(x,dim,lag,'euclidean'),...
% dim,lag,e,[],[],l_min,v_min,1,...
% 'euclidean','nonormalize','silent')
%
% Examples: a=randn(300,1);
% crqa(a,1,1,.2,40,2,'euc')
%
% N=500; w=40; ws=2;
% a=3.4:.6/(N-1):4;
% b=.5; for i=2:N, b(i)=a(i)*b(i-1)*(1-b(i-1));end
% y=crqa(b,3,2,.1,w,ws);
% subplot(2,1,1), plot(a,b,'.','markersize',.1)
% title('logistic map'), axis([3.4 4 0 1])
% subplot(2,1,2), plot(a(1:ws:N-w),y(1:ws:N-w,1))
