WARNING: deprecated function.
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
Note
This function is used in the CalculateFracDim function, which is
deprecated. We suggest the use of the CalculateCorrDim function
instead of CalculateFracDim.
