Description

32-digit values of the first 100 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=log^2(1-a*exp(-|x|)) on [-Inf,Inf], a = 1/2, are computed by a moment-based method using the routine sr_sqgbinet(dig,32,100,1/2), where dig=64 has been determined by the routine dig_sqgbinet(100,1/2,56,4,32). For the respective moments, see W. Gautschi and G.V. Milovanović, "Binet-type polynomials and their zeros", Electron. Trans. Numer. Anal., to appear. The software provided in this dataset allows generating an arbitrary number N of recurrence coefficients for any parameter a, 0 < a < 1, and to any precision.
