fr.cnes.sirius.patrius.math.analysis.integration.gauss.LegendreRuleFactory

public class LegendreRuleFactory
extends BaseRuleFactory<Double>

Factory that creates Gauss-type quadrature rule using Legendre polynomials. In this implementation, the lower and upper bounds of the natural interval of integration are -1 and 1, respectively. The Legendre polynomials are evaluated using the recurrence relation presented in .
