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)=phi_m(x) on [0,m], m=10, are computed by a multicomponent discretization procedure using the routine sr_cBspline_dis(34,32,100,10) called by run_cBspline.m. For details concerning the discretization, see Section 3 in Walter Gautschi, "Polynomials orthogonal with respect to cardinal B-spline weight functions", Numerical Algorithms, submitted. The results obtained are in complete agreement with the thirty 20-digit recurrence coefficients given in Section 3 of Gradimir V. Milovanović, "Symbolic-numeric computation of orthogonal polynomials and Gaussian quadratures with respect to the cardinal B-spline", Numerical Algorithms, to appear. The software provided in this dataset allows generating an arbitrary number N of recurrence coefficients for arbitrary order m and for different precisions.
