polynomial interpolation function

基本解释

Lastly, using the compactly supported radial functional to take the place of the polynomial function, local radial point interpolation method, is presented in this paper.
最后，本文采用紧支距离基函数取代多项式基函数，提出了局部径向点插值方法，这是一种真正意义上的无网格方法。
One is the formula of central difference based on isometric node of interpolation polynomial, and the other is fitting an original function, afterwards finding its derivation.
针对这一实际情况，首先从经典差分模型入手，推导出了环境激励下的多参考点互相关差分模型，然后分别采用增广矩阵法和多项式特征值法求解模态参数。
On the basis of the periodicity of the designed orbit of GPS satellite, trigonometric function polynomial interpolation method is used to interpolate the IGS precise ephemeris.
考虑到GPS卫星的设计轨道具有明显的周期性，用三角函数多项式方法进行精密星历插值，并与经典的拉格朗日插值方法进行了比较。
