In order to calculate de Fractal Dimension and Approximate Entropy (or others properties of the data) a representation of the data in a space m-dimensional is needed
Usage
BuildTakensVector(HRVData, Data, m, tau)
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
Value
Returns a matrix with the Expanded Data with N-(m-1)*tau rows (N is the length of the Data to be analyzed) and m columns
