//=== === === === === === === =
//函数说明
//函数名称:PolyFit
//函数功能:最小二乘法曲线拟合
//使用方法:double *x ---- 存放n个数据点的X坐标
// double *y ---- 存放n个数据点的Y坐标
// int n -------- 给定数据点个数
// double *a ---- 返回m-1次拟合多项式的m个系数
// int m -------- 拟合多项式的项数,即拟合多项式的最高次为m-1。要求m20,则本函数自动按m=min{n,20}处理
// double *dt --- dt[0]返回拟合多项式与各数据点误差的平方和;dt[1]返回拟合多
// 项式与各数据点的误差绝对值之和;dt[2]返回拟合多项式与各数据
// 点误差绝对值的最大值
//注意事项:拟合多项式的形式为 y = b0 + b1*(x-Xavr)...

基于c实现单片机的键盘控制
本代码主要实现了基于89c52单片机实现矩阵键盘的程序,主要体现了分为横扫描以及竖扫面的主体思想,实现对矩阵键盘的控制,并结合数码管的显示来验证此程序的正确性。在使用此程序之前,要人为的去修改硬件资源程序部分,使之程序的思路是根据此程序来的,但是具体的硬件资源是根据手里所有的开发板来进行修改的,这样可以很好的适合于每个平台。此代码为c代码有很好的移植性以及易懂性
