Cross Recurrence Plot Toolbox 5.24 (R34)

CRP Toolbox

rrspec

Tau-recurrence rate spectrum.

Syntax

rrspec(x,m,t,e,w,fs,...)
p=rrspec(...)
[p f]=rrspec(...)

Description

rrspec(x,m,t,e,w,fs,...) calculates the tau-recurrence rate spectrum based on a recurrence plot using embedding dimension m, embedding delay t, recurrence threshold e, maximal lag for tau-recurrence w, and sampling frequency fs. The input arguments are similar to those of the command taucrp.

p = rrspec(...) returns the tau-recurrence rate spectrum in vector p.

[p f] = rrspec(...) returns the tau-recurrence rate spectrum in vector p and the vector of corresponding frequencies f.

Example

fs = 22;
x = sin(2*pi * [0:1/fs:44]);
rrspec(x,2,1,.1,[],fs)
