RHRV (version 2.4)

CalculateRfromCorrelation: Calculates ra and rb from Correlation

Description

Calculates ra and rb distances that verify that their correlation values are Cra and Crb

Usage

CalculateRfromCorrelation(HRVData, Data, m, tau, Cra, Crb)

Arguments

HRVData

Data structure that stores the beats register and information related to it

Data

Portion of HRVData to be analyzed

m

Value of the dimension of the expansion of data

tau

Delay of the expansion of data

Cra

Minimum value of correlation for calculating Fractal Dimension

Crb

Maximum value of correlation for calculating Fractal Dimension

Value

• Returns a 2 by 2 matrix containing ra and rb distance in the first row and their exact correlation values in the second row
