输入信号采用4阶M序列的二阶系统的最小二乘一次完成算法辨识程序(Input signal using M sequence of order 4 second-order system least squares algorithm for a complete identification process)

Binary FSK Modulation

Makes 3d scatter plot much faster than scatter3

说明：  一个数如果恰好等于它的因子之和，这个数就称为“完数”，编写程序找出2～5000中的所有完数。(If a number is just equal to the sum of its factors, this number is called &quot complete number&quot , written procedures to identify 2 to 5000 in the number of all finished.)
