<p>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=2, are computed by a multicomponent discretization procedure using the routine sr_cBspline_dis(dig,32,100,2) called with the commands &#39;global dig; dig=34&#39;, where dig=34 has been determined by the routine dig_Bspline_dis(100,2,32,2,32), attesting to the high stability of the multicomponent discretization procedure. The results are in complete agreement with those produced by sr_cBspline_cheb.m (cf. doi:10.4231/R7 . . . ), but are obtained ten times as fast. For details concerning the discretization, see Section 3 in Walter Gautschi, &quot;Polynomials orthogonal with respect to cardinal B-spline weight functions&quot;, Numerical Algorithms, submitted. The software provided in this dataset allows generating an arbitrary number N of recurrence coefficients for arbitrary order m and for different precisions.</p>
