After I create recurrence matrix using "crp" function and I get a recurrence matrix, can I calculate RQA from this matrix?
I read your manual but it seems all function needed "time series" as input.
% create recurrence plot
X = crp(timeseries,'silent');
% get distributions of line lengths
% (actually you should apply here the Theiler window before, but I omit it for simplification)
[m l] = dl(X); % l is a list of all line lengths of diagonal lines
[m v] = tt(X); % v is a list of all line lengths of vertical lines
% recurrence rate
mean(X(:))
% determinism
sum(l(l>=lmin))/sum(X(:)) % where lmin is the minimal diagonal line length, e.g. lmin=2
% mean diagonal line length
mean(l(l>=lmin))
% maximal diagonal line length
max(l(l>=lmin))
% entropy
histL=hist(l,1:length(X));
entropy(histL(:));
