d01apf © Numerical Algorithms Group, 2002.

Purpose

D01APF 1-D quadrature, adaptive, finite interval, weight function with end-point singularities of algebraico-logarithmic type

Synopsis

[result,abserr,w,iw,ifail] = d01apf(g,a,b,alfa,beta,epsabs,epsrel<,key,lw,...
liw,ifail>)

Description

 
 D01APF integrates a function of the form g(x)w(x), where the 
 weight function w(x) may have algebraico-logarithmic 
 singularities at the end-points a and/or b.
