首先讨论了Hermite三角插值的收敛性问题,然后利用Hermite反三角插值公式建立了反周期函数正常积分的求积公式,最后通过分离奇点的方法建立了含余割核奇异积分的求积公式.
The convergence of Hermite trigonometric interpolation is discussed firstly, and then a quadrature for the proper integral of 2π-antiperiodic functions is established by Hermite antl-trigonometric interpolation. Finally the quadrature formulae of corresponding singular integrals with kernel csc (t-x)/2 are derived by using the method of separation of singularity.
