This eigenvalue problem is called the Hermite equation, although the term is also used for the closely related equation ″ ′ =. whose solution is uniquely given in terms of physicist's Hermite polynomials in the form () = (), where denotes a constant, after imposing the boundary condition that u should be polynomially bounded at infinity.
where now the closed path C encircles the origin. In the equation for (,), is an implicit function of . As examples, we will find the generating functions for the Hermite polynomials and the Legendre polynomials. The Hermite polynomials are particularly easy: =
Every Hermite-like polynomial sequence can have its domain shifted and/or scaled so that its interval of orthogonality is (,), and has Q = 1 and L(0) = 0. They can then be standardized into the Hermite polynomials.
In mathematics, the discrete q-Hermite polynomials are two closely related families h n (x;q) and ĥ n (x;q) of basic hypergeometric orthogonal polynomials in the basic Askey scheme, introduced by Al-Salam and Carlitz . Roelof Koekoek, Peter A. Lesky, and René F. Swarttouw (2010, 14) give a detailed list of their properties.
The four Hermite basis functions. The interpolant in each subinterval is a linear combination of these four functions. On the unit interval [,], given a starting point at = and an ending point at = with starting tangent at = and ending tangent at =, the polynomial can be defined by = (+) + (+) + (+) + (), where t ∈ [0, 1].
Then solve the differential equation representing this eigenvalue problem in the coordinate basis, for the wave function | = (), using a spectral method. It turns out that there is a family of solutions. In this basis, they amount to Hermite functions, [6] [7] =!
The Schrödinger equation is a partial differential equation that governs the wave function of a non-relativistic quantum ... are the Hermite polynomials of order ...
The function receives a real number x as an argument and returns 0 if x is less than or equal to the left edge, 1 if x is greater than or equal to the right edge, and smoothly interpolates, using a Hermite polynomial, between 0 and 1 otherwise. The gradient of the smoothstep function is zero at both edges.
