An algorithm for calculating the Hurst exponent is presented, which allows one to evaluate the degree of chaotization of the signal in question. The capabilities of various multifractal analysis programs are shown, which require the use of different mathematical models. %K Multifractal %K Herst Indicator %K Heart Rate %K Deterministic Chaos %K Software %U http://www.oalib.com/paper/5435499
