摘要
为更好地提高拟插值算子的精度,文章对MQ拟插值算子的构造及其相关性质进行改进,得到一种具有3次方精度的拟插值算子。数值实验表明改进的拟插值具有良好的逼近精度。
In order to improve the accuracy of the quasi-interpolation operator, the construction of MQ quasi-interpolation operator and its related properties are improved in this paper, a quasi interpolation operator with 3 cubed accuracy is obtained. Numerical experiments show that the improved quasi interpolation has good approximation accuracy.
