You may have heard that PURR may be down temporarily this Thursday (10/17) for maintenance. The maintenance is being rescheduled, and we do not expect to have any downtime this week. We will let you know when the maintenance has been rescheduled. close

Description

32-digit values of the first 100 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=(1-x)^a*(1+x)^b on [c,1], c=0, a=-1/2, b=1/2, are computed by a 2-component discretization procedure using the routine sr_upper_subrange_jacobi(32,100) with (global) input parameters dig=34, c=0, a=-1/2, b=1/2. The procedure is analogous to the one for lower subrange Jacobi polynomials, described in Section 2 of Walter Gautschi, "Sub-range Jacobi polynomials", Numerical algorithms 61 (2012), 649-657. doi: 10.1007/s11075-012-9556-z. The software provided in this dataset allows generating an arbitrary number N of recurrence coefficients for arbitrary parameters -1 < c < 1, a > - 1, b > -1 and for different precisions.
