testP: Periodic solution test

In GPoM: Generalized Polynomial Modelling

Periodic solution test

Description

Tests if a trajectory is periodic.

Usage

testP(data, wthresh = 0.1, fxPtThresh = 1e-04, show = 0)

Arguments

data	Input Time series: Each column is one time series that corresponds to one variable.
wthresh	Threshold used to detect the limit cycle.
fxPtThresh	Threshold used to detect fixed points.
show	Provide (2) or not (0-1) visual output during the running process.

Value

periodic An integer classifying the models: diverging or unclassified trajectory (0), period-1 trajectory (-1), period-2 trajectory (-2) and fixed Point (2).

Examples

#Example
# Load data:
data('P1FxChP2')
# Test a period-1 trajectory
testP(P1FxChP2[,1:2], wthresh=0.1, fxPtThresh = 1e-6, show=0)
# Test a Fixed Point trajectory
testP(P1FxChP2[,3:4], wthresh=0.1, fxPtThresh = 1e-6, show=0)
# Test a chaotic trajectory
testP(P1FxChP2[,5:6], wthresh=0.1, fxPtThresh = 1e-6, show=0)
# Test a period-2 trajectory
testP(P1FxChP2[,7:8], wthresh=0.1, fxPtThresh = 1e-6, show=0)
