Hermite series expansion
Witryna11 kwi 2024 · Aiming at the problem of sparse measurement points due to test conditions in engineering, a smoothing method based on zero-padding in the wavenumber domain is proposed to increase data density. Firstly, the principle of data extension and smoothing is introduced. The core idea of this principle is to extend the discrete data … Witrynapower series case, however, one cannot show that a lower bound in (2.2) is also (changing the sign of e) an upper bound because the actual rate of convergence must …

The probabilist's Hermite polynomials are solutions of the differential equation. where λ is a constant. Imposing the boundary condition that u should be polynomially bounded at infinity, the equation has solutions only if λ is a non-negative integer, and the solution is uniquely given by , where denotes a constant.
