快速排序算法的c实现

给定一块宽度为W的矩形板，矩形板的高度不受限制。现需要从板上分别切割出n个高度为hi，宽度为wi的矩形零件。切割的规则是零件的高度方向与矩形板的高度方向保持一致。要求求出一种切割法使得所使用的矩形板的高度h最小．用递归及分治法解此问题-given a width of the rectangular plate W, the height of rectangular plate unrestricted. Board is required from the respective cut out n height of the hi, wi width of the rectangular parts. Cutting parts to the rules of the height of the rectangular plate with a high degree of consistent direction. Asked obtained a law made by cutting the use of the rectangular plate height h minimum. Using recursive and partition Solving this problem

可以作为有限元学习的编程实例，以更好地理解有限元理论，并为进一步使用大型有限元软件打下基础。本文所涉及的有限元基本理论请参考章本照先生编著的《流体力学中的有限元方法》PP.156-165。-FEM can be used as learning programming examples to better understand the finite element theory, and to further the use of large-scale finite element software lay the groundwork. This paper involved the theory of finite element please refer to the chapter as a sign that the President "hydrodynamics of the finite element method" PP. 156-165.
