Boost C++ Libraries: Ticket #9927: Bug in zero's finding of bessel functions https://svn.boost.org/trac10/ticket/9927 <p> The zero finding routine for cylindrical bessel functions gives incorrect values for a large number of nodes for a variety of orders. Examples are </p> <p> order = 3/2, first zero. Reported at 8.3825 but should be at 8.1825, i.e. 0.2 lower. I check refined all first 100 zeros up to order 100+1/2 using a golden section search against a spherical bessel function. Where there are errors, they are always 0.2. </p> <p> </p> en-us Boost C++ Libraries /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9927 Trac 1.4.3 Peter Zwart <PHZwart@…> Mon, 21 Apr 2014 21:05:26 GMT <link>https://svn.boost.org/trac10/ticket/9927#comment:1 </link> <guid isPermaLink="false">https://svn.boost.org/trac10/ticket/9927#comment:1</guid> <description> <p> After applying patch </p> <p> <a class="ext-link" href="https://github.com/boostorg/math/commit/9f8ffee4b7a3f82b1c582735d43522d7d0cde746"><span class="icon">​</span>https://github.com/boostorg/math/commit/9f8ffee4b7a3f82b1c582735d43522d7d0cde746</a> </p> <p> the problem went away. </p> <p> Problem solved! </p> </description> <category>Ticket</category> </item> <item> <author>Peter Zwart <PHZwart@…></author> <pubDate>Mon, 21 Apr 2014 21:06:30 GMT</pubDate> <title>severity changed https://svn.boost.org/trac10/ticket/9927#comment:2 https://svn.boost.org/trac10/ticket/9927#comment:2 <ul> <li><strong>severity</strong> <span class="trac-field-old">Problem</span> → <span class="trac-field-new">Cosmetic</span> </li> </ul> Ticket John Maddock Tue, 22 Apr 2014 11:10:41 GMT <link>https://svn.boost.org/trac10/ticket/9927#comment:3 </link> <guid isPermaLink="false">https://svn.boost.org/trac10/ticket/9927#comment:3</guid> <description> <p> So can I close this issue now? </p> </description> <category>Ticket</category> </item> <item> <dc:creator>John Maddock</dc:creator> <pubDate>Sat, 04 Oct 2014 12:21:57 GMT</pubDate> <title>status changed; resolution set https://svn.boost.org/trac10/ticket/9927#comment:4 https://svn.boost.org/trac10/ticket/9927#comment:4 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">worksforme</span> </li> </ul> Ticket
