摘要
本文描述了任意三角域上Ｃ１有理插值的一种布尔和方法．这种方法构造简单，计算方便，逼近精度为Ｏ（ｈ９），代数精度集为｛ｘｉ，ｙｊ，０≤ｉ＋ｊ≤３｝．最后给出了一个数值例子．
In this paper,a Boolean Sum algorithm is presented for constructing C1 rational interpolation function over an arbitrary triangles. The algorithm is simple to construct and easy to calculate,and its approximate order is 0(h9).Its algebraic precision set includes all polynomials of degree≤3.Finally, a numerical example is given.
