本文指出:在任意不规则的非矩形二维网格上,若采用两步展开的做法,即首先逐行展开,再按列展开就可以对在该网格上给定的函数实现二维车贝雪夫多项式展开。这一推广在实用上有很大的意义。
In this paper, we point out that if we use two-step expansion on any irregular non-rectangular 2D grid, we expand it first line by line and then expand the column to realize the 2D vehicle for the given function on the grid Bexhev polynomial expansion. This promotion is of great practical significance.
