杜金元等在2004年给出了Hermite仿三角多项式插值问题的基函数,且在插值函数具有一定解析性的条件下给出了余项公式。本文给出了反周期函数的一种Hermite仿三角多项式插值逼近,其对任意反周期连续函数都是收敛的。我们给出了收敛速度的一种估计。
Jinyuan Duet al. got the fundamental Hermite paratrigonometric polynomials in 2004, they also gave the remainder term when the interpolated functions possess certain analyticity. We give a kind of paratrignometric Hermite interpolation which is convergent for any antiperiodic continuous function. An estimate for its convergence rate is derived.
