Hace 3 días · Prony’s method is a classical algorithm to find an approximation of an exponential sum. We present an algorithm modified to improve the numerical behavior of the classical Prony method. 28 The algorithm utilizes a special form of the SVD for complex symmetric matrices to calculate singular values of the square Hankel matrix 28,29
Hace 5 días · Introduction to Linear Algebra with Mathematica. Glossary. Preface. In this section, we show that Bessel's functions. ϕn(x) = Jν(μnx ℓ) (n = 1, 2, 3, …) are orthogonal when parameters μ n are positive roots of some transcendent equation involving Bessel functions of the first kind. Orthogonal means that.
Hace 2 días · Definition and uses. A Green's function, G(x,s), of a linear differential operator L = L(x) acting on distributions over a subset of the Euclidean space , at a point s, is any solution of. (1) where δ is the Dirac delta function. This property of a Green's function can be exploited to solve differential equations of the form.
Hace 3 días · Larry Hankel, the owner of a local trucking company, reported that someone had broken into one of his box trucks over the weekend and stolen 10 rims. Hankel discovered the theft when he arrived at work and found the lock cut and the rims missing, according to the affidavit of probable cause.
Hace 5 días · Diophantine approximation in function fields gives rise to many combinatorial questions. One interesting question is the computation of the Hausdorff dimension of the set of badly approximable formal Laurent series. Those series are tightly connected to Hankel matrices with specific properties.
Hace 1 día · The superconductivity of CaC6 as a function of pressure and Ca isotopic composition was revisited using DFT calculations on a 2c–double hexagonal superlattice. The introduction of superlattices was motivated by previous synchrotron absorption and Raman spectroscopy results on other superconductors that showed evidence of superlattice vibrations at low (THz) frequencies. For CaC6 ...
