摘要
本文推导出被积函数f(x)具有极点且其极点可与正交多项式Pn(x)零点相重合的情形的改进Gauss型求积公式,并给出了数值计算的例子。
A modified Gaussian quadrature formula is derived for the numerical evaluation of integral of the from w(x)f(x)dx, where f(x) possesses poles and some of them coincide with the zeros of an orthogonal polynomial pn(x), two numerical examples are provided to illustrate the formula.
