<p style="color: grey"> Python recipe 576900 by <a href="/recipes/users/924636/">Gabriel Genellina</a> (<a href="/recipes/tags/algorithms/">algorithms</a>, <a href="/recipes/tags/area/">area</a>, <a href="/recipes/tags/integration/">integration</a>, <a href="/recipes/tags/math/">math</a>). </p> <p>The Gaussian quadrature is among the most accurate integration scheme for smooth integrands. It replaces a integral by a sum of sampled values of the integrand function times some weight factors.</p> <p>This is strictly a minor rewrite of <a href="http://code.activestate.com/recipes/52292/">recipe 52292</a>, just to make it compatible with Python 2.4 and above. 2to3 converts it perfectly to be used with Python 3.x</p> <p><em>All</em> credit is due to the original author, Alexander Pletzer.</p>
