Section headings of       the Timofeev and Hearn problems and file names of the Rubi development       testsuite are indicative of content. And the files can be downloaded       and searched for special functions of your interest.              These problem collections serve as a means of quantifying integrator       performance and identifying performance gaps (named suites), or as an       insurance against performance regression (Rubi development suite). I       have never felt the need for any sort of index.              Martin.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
