摘要
本文给出一般曲边三角形域上一种构造高代数精确度,且不含内部节点的新的边界插值公式——带微商项的边界插值公式。
Let T denote a region bounded by a curvilinear triangle, i,e T={(x,y); 0≤x≤1, 0≤y≤f(x)}, where f(x) is a strictly monotonic continuous function on [0,1]. In this article, we introduce a new interpolation scheme of boundary type for T involing derivative term which possess n-th (with arbitrary n)algebraic exactitude.
