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/(exp(x)+1)]^r on [0,Inf], r=2, are computed by a moment-based method using the routine sr_fermidirac(dig,32,100,2), where dig=168 has been determined by the routine dig_fermidirac(100,2,160,4,32). For the respective moments, see Section 5 of Walter Gautschi, "Variable-precision recurrence coefficients for nonstandard orthogonal polynomials", Numerical Algorithms 52 (2009), 409-418. doi: 10.1007/s11075-009-9283-2. The software in this dataset allows generating an arbitrary number N of recurrence coefficients for an arbitrary integer r > 0 as well as for different precisions.
