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 65 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=x^a*exp(-x)*log(1+1/x) on [0,Inf], a=-1/2, are computed by a 2-component discretization method using the routine sr_explogalgm1half0inf(32,65), where dig=48 has to be entered when prompted by the routine. The value 48 of dig has been determined by the routine dig_algm1halfexplog(32,4,32). The software provided in this dataset allows generating any number N <= 65 of recurrence coefficients for any noninteger a > -1, as well as for different precisions.
