Description
32-digit values of the first 100 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=x^{1/2}/(exp(x)-1) on [0,Inf] are computed by a moment-based method using the routine sr_theodorus(dig,32,100), where dig=124 has been determined by the routine dig_theodorus(100,116,4,32). For the respective moments, see Section 4.2 of Walter Gautschi, "The spiral of Theodorus, numerical analysis, and special functions," Journal of Computational and Applied Mathematics 235 (2010), 1042-1052. doi: 10.1016/j.cam.2009.11.054. The software in this dataset allows generating an arbitrary number N of recurrence coefficients to any precision.
