In numerical analysis, transfinite interpolation is a means to construct functions over a planar domain in such a way that they match a given function on the boundary. This method is applied in geometric modelling and in the field of finite element method. The transfinite interpolation method, first introduced by William J. Gordon and Charles A. Hall,〔 receives its name due to how a function belonging to this class is able to match the primitive function at a nondenumerable number of points. In the authors' words: == Formula == With parametrized curves , describing one pair of opposite sides of a domain, and , describing the other pair. the position of point (u,v) in the domain is \begin \vec(u,v)&=&(1-v)\vec_1(u)+v\vec_3(u)+(1-u)\vec_2(v)+u\vec_4(v)\\ && - \left() \end where, e.g., is the point where curves and meet. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Transfinite interpolation」の詳細全文を読む スポンサード リンク
