CalculateRfromCorrelation function

Calculates ra and rb from Correlation

WARNING: deprecated function. Calculates ra and rb distances that verify that their correlation values are Cra and Crb

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

Returns

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