SRJAC: Sub-range Jacobi polynomials

10.4231/R7JS9NCR

Walter Gautschi

04/23/2014

Orthogonal polynomials relative to the Jacobi weight function, but orthogonal on a strict subinterval of [-1, 1] are studied, in particular with regard to their numerical computation. Related Gaussian quadrature rules are also considered.

Walter Gautschi

04/23/2014

Matlab software are presented for generating Gauss–Turán quadrature rules for the Laguerre and Hermite weight functions to arbitrarily high accuracy. This is accomplished by the Newton–Kantorovich method, using initial approximations that are sufficiently...
