Class LegendreHighPrecisionRuleFactory

java.lang.Object

org.apache.commons.math3.analysis.integration.gauss.BaseRuleFactory<BigDecimal>

org.apache.commons.math3.analysis.integration.gauss.LegendreHighPrecisionRuleFactory

public class LegendreHighPrecisionRuleFactory
extends BaseRuleFactory<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.
