说明：  这是数字信号处理课程中的AR模型的功率平铺攻击MATLAB编程(This is a digital signal processing courses in the AR model of power tile attack MATLAB Programming)

C=CURVEFIT( 拟合模型 ,参数C初值,X数据,Y数据) 求参数C使得 sum {(FUN(C,X数据)-Y数据).^2}最小化(C = CURVEFIT ( fitting model and parameter C, initial X, Y data) for data parameters that sum {there (C) (C, X-ray data- Y j ^ 2) minimizing})

此程序写了，任意给定两个数，互相作为底数和指数，再求和。如果不满足条件，报错。(This program was made, any given two numbers to each other as the base and index, and then sum. If does not meet the conditions, an error.)
