最小二乘法中代数多项式曲线拟合的分析及实现

摘要

最小二乘法是广泛使用的数据分析方法,它通过一组实验数据,按残差平方和最小准则,寻求一个解析函数,从而描述几个变量之间的关系.论文介绍了求解最小二乘法中代数多项式曲线拟合的数学关系,并给出了通用的C语言程序被调用函数.%The method of least square is a widely used data analysis methods, it is through a set of experimental data, according to the rule of minimum residual sum of squares, seeking an analytic function, which describes the relationship of several variables.Were introduced in this paper to solve the least squares polynomial curve fitting mathematical relationships, and gives the general C programming language of the called function.
