摘要:拉格朗日插值法是广泛使用的插值方法,不仅在数学,更广泛的应用在工程和计算机科学,展现的是一种数学思想方法同样也是非常重要的,这个话题在前人的基础上进一步研究拉格朗日插值算法,并在实际生活中的应用。拉格朗日多项式插值被用于各种研究领域中。梁学章教授1965首次将唯一的多元拉格朗日插值的解到一个类似的几何问题,所以我们必须研究多元多项式插值理论和方法问题解的唯一性,比如可以利用代数几何,所以我们可以学习多元多项式插值的理论来解决使用代数几何方法的问题。添加直线法和曲线法是他构建的平面插值方法可解群,从而解决了多元拉格朗日插值问题进一步突破。39174 毕业论文关键词:拉格朗日插值算法;MATLAB;信息隐藏
Lagrange Interpolation Algorithm And Its Implementation
Abstract: Lagrange polynomial interpolation method is widely used, not only in mathematics, but also widely used in engineering and computer science, is a mathematical way of thinking is also very important to show, this topic in previous Further research based on Lagrange interpolation algorithm, and applied in real life. Professor Liang Xuezhang in 1965 for the first time will be the only solution multivariate Lagrange interpolation into a similar geometry problems, theoretical issues and constructors a unique solution pluralism so we need to study polynomial interpolation, for example, algebraic geometry can use, so we can Learning Theory multivariate polynomial interpolation method to solve problems using algebraic geometry. Add a straight-line method and add conic method is to construct his plane interpolation method solvable only important point group, which makes solving multivariate Lagrange interpolation problem has been further breakthrough.
Key words: Lagrange interpolation algorithm, MATLAB, Information Hiding
