代码说明：

  利用y(n)=x(n)-y^2(n-1)+y(n-1)， x(n)=au(n),u(n)为阶跃序列，这一算法，计算了0.001-0.999之间数字的平方和，并给出图形，并与matlab自身的函数power进行了比较，给出了差值的图形(Calculates the square sum of the Numbers between 0.001 0.999, and the graphics is given, and with the function of matlab power are compared, and the difference of the graphics is presented)
