HermiteRuleFactory (Hipparchus 3.0 API)

java.lang.Object
- org.hipparchus.analysis.integration.gauss.AbstractRuleFactory
- - org.hipparchus.analysis.integration.gauss.HermiteRuleFactory

All Implemented Interfaces:

RuleFactory
```
public class HermiteRuleFactory
extends AbstractRuleFactory
```
Factory that creates a Gauss-type quadrature rule using Hermite polynomials of the first kind. Such a quadrature rule allows the calculation of improper integrals of a function
\(f(x) e^{-x^2}\)

Recurrence relation and weights computation follow Abramowitz and Stegun, 1964.

    Computes the rule for the given order.
    
    Specified by:
    
    computeRule in class AbstractRuleFactory
    
    Parameters:
    
    numberOfPoints - Order of the rule to be computed.
    
    Returns:
    
    the computed rule.
    
    Throws:
    
    MathIllegalArgumentException - if the elements of the pair do not have the same length.
