rrspec

Purpose

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)
