Witryna2 lis 2014 · In general, the (polynomial) division of one Hermite series by another results in quotient and remainder terms that are not in the Hermite polynomial basis set. Thus, to express these results as a Hermite series, it is necessary to “reproject” the results onto the Hermite basis set, which may produce “unintuitive” (but correct) results ... WitrynaA primary examples is the solution of differential equations with fourth-order derivatives where standard finite element formulations lead to a need for basis functions with continuous first-order derivatives. The most common type of such basis functions in 1D is the so-called cubic Hermite polynomials. psrb ct agenda

Witryna1 sty 1985 · The basic idea of the algorithm is to recursively construct a Hermite reduced lattice basis. To that end, an 'almost' reduced basis is constructed that has the following property: There exists an easily computable set of 'moderate' size that contains a shortest nonzero lattice element. All elements of this set are 'tried out'. http://hplgit.github.io/INF5620/doc/pub/H14/fem/html/._main_fem007.html
