摘要
通过证明给出了柯西主值积分四点求积公式的一组参数优化值,以及一定限制下的误差公式,并通过数值实例验证了对某些函数,其误差小于Price公式。
In this paper,the anthor gives the construction of four point-quadrature rule of Cauchy prinapal value of an integral by parameter optimisation.Concurrently,the anthor gives an error formular under the certain restruction.Real instance test proves that its error is smaller than price formular to some function.
