资源简介:
<p> 32-digit values of the first 100 recurrence coefficients for orthogonal polynomials relative to the weight function w(x)=x^a*[log(1/x)]^b on [0,1], a = 1/2, b = 3, are computed by a moment-based method using the routine sr_l_alglog(dig,32,100,1/2,3), where dig = 176 has been determined by the routine dig_l_alglog(100,1/2,3,168,4,32). The software provided in this dataset allows generating an arbitrary number N of recurrence coefficients for arbitrary a > -1, b > -1, as well as for different precisions. If the singularities, with the same exponents, occur at the right endpoint, then the alpha-coefficients must be replaced by 1 minus the present ones, whereas the beta-coefficients remain the same.</p>
