Research direction

Review the listed candidates and the linked issues for the Von Mises distribution, Gauss-Hermite quadrature, generalized Laguerre polynomials, and interpolation with different units. The issue does not identify an entry point, file, test, or single feature, so work is not defined as complete until one proposal has a concrete scope and acceptance criteria.

Written by the indexing model from the issue text.

Description

enhancement
  • Modified Clenshaw recurrence for all special functions governed by 3-term recurrence relations.
  • Higher dimensional interpolation (Akima has a natural generalization to higher dimensions, but there's some work on getting the API correct.)
  • Prolate spheroidal wavefunctions
  • Higher dimensional quadrature; sparse grids for medium dimensionality, extensions of Gaussian quadrature in lower dimensions.
  • Wavelet transforms, shearlets
  • Bivariate interpolation and quadrature at the Padua points
  • Gauss-Hermite quadrature
  • Genz-Kaister
  • Generalized Laguerre polynomials
  • Interpolation with different units
  • Make further progress on zeta, phi and friends (Lerch phi transcendent, polylog, and more).
  • FFT

What else is a natural fit for the library, and is useful?
