6.7 corrsum - Computation of the correlation sum

The topics correlation sum and correlation dimension estimation can also be found here.

Syntax:

Input arguments:

Output arguments:

Example:

 
x = chaosys(25000, 0.025, [0.1 -0.1 0.02], 0);  % generate data from Lorenz system
x = x(5001:end,:);      % discard first 5000 samples due to transient
% now compute correlation sum up to five percent of attractor diameter
[c,d] = corrsum(x, randref(1,20000, 1000), 0.05, 0);
loglog(d,c)     % and show the result as log-log plot
