轻松用c++实现线性选择算法
资源描述元素选择问题
给定线性序集中的n个元素和一个整数k,1≤k≤n,要求找出这n个元素中第k小的元素。
当k=1时——找最小元素;
当k=n时——找最大元素;
当k=(n+1)/2——找中位数
算法设计思想
与快速排序算法的设计思想基本相同,即对输入数组进行递归划分,但操作上只对划分出的两个子数组中的一个进行进一步的递归处理;

程序:全主元Gauss消去法
过程:gaussq(aa,bb,xx,n,sgn)
作用:aa为系数矩阵,bb为右端向量,xx为解向量,n为方程阶数,sgn为标识符,1表示计算正常进行,0表示计算失败
方程形式为:aa(n,n)*x(n)=bb(n)-Procedure: All the main element Gauss elimination process: gaussq (aa, bb, xx, n, sgn) Role: aa for the coefficient matrix, bb for the right-hand side vector, xx for the solution vector, n the order of the equation, sgn as identifiers, 1 indicates the calculation as normal, 0 indicates failure of the calculation equation of the form: aa (n, n)* x (n) = bb (n)

误差分析的方法有多种,例如,威点逊(J. H. Wilkison)针对的计算机的浮点运算提出的“向后误差分析”,这是一种先验估计误差的方法,较以往的“向前误差分析”在矩阵运算的舍入误差估计上有较好的结果,以而使矩阵的误差分析获得了突破性的进展,使不少用向前误差分析难于判定可靠性的数值方法获得新的进展。-error analysis by a number of means, for example, Granville point Morrison (J.
