最小二乘逼近（least-squares approximation）得到一组离散（discrete）数据点的近似函数（approximating function），实验数据往往是用最小二乘逼近得到一条秘密曲线（curve fitting）。下面概述的是最小二乘近似作为多项式的近似函数，除了多项式外，指数的几个右公式也可以作为类似的函数使用。关于最小平方近似的计算原理，请参考市场上的数值分析书籍

SPLASH is a c++ class library that implements many of the Perl constructs and data types, including extensive regex regular expression pattern matching. For those not familiar with Perl, it is an excellent scripting language by Larry Wall and is available for most platforms. This Class library provides List, String, Regular Expression, and text manipulation handling capabilities based on those provided in Perl

基于SQL Server数据库和JAVA语言的学生信息管理系统；完整源代码，JAVA语言实现，NetBeans开发环境，可以导入Eclipse

一元稀疏多项式计算器的基本功能是： (1)输入并建立多项式； (2)输出多项式，输出形式为整数序列：n,c1,e1,c2,e2,….,cn,en, 其中n是多项式的项数，ci和ei分别是第I项的系数和指数，序列按照指数降序排列； （3）多项式a和b相加，建立多项式a+b （4）多项式a和b相减，建立多项式a-b.-Sparse Polynomial calculator a dollar a basic function is to: (1) input and the establishment of polynomials (2) the output polynomial, the output sequence of the form of an integer: n, c1, e1, c2, e2, ...., Cn , en, in which n is the number of polynomial, ci and ei, respectively, is the first I of the coefficient and index, sequence in accordance with the index in descending order (3) polynomials a and b are added together to establish polynomial A2B ! b (4) polynomials a and b-phase reduction, the establishment of polynomial ab.
