The results of the tests show that for the modified Schur-Cohn sequence with Chebyshev polynomials, increasing of the length of the coefficients occurs, but not so intensively as it occurs for most of polynomials. For Sturm sequences with Chebyshev polynomials, the length of the coefficients ...
HBF coefficients (15 features): each beat segment, here defined by the samples located 250 ms before and after each R spike, is decomposed using 3, 4, and 5 Hermite functions as described in [21]. The coefficients obtained from fitting Hermite polynomials of degrees 3, 4, and 5 are calc...
