org.apache.commons.math4.analysis.integration.gauss.BaseRuleFactory<java.math.BigDecimal>
org.apache.commons.math4.analysis.integration.gauss.LegendreHighPrecisionRuleFactory
public class LegendreHighPrecisionRuleFactory
extends BaseRuleFactory<java.math.BigDecimal>
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 Abramowitz and Stegun, 1964.
