二阶系统的最小二乘一次完成算法辨识程序，图形的横坐标是采样时刻i, 纵坐标是输出观测值z, 图形格式为连续曲线-second-order system of least-squares algorithm for a complete identification procedures, graphics abscissa is the sampling time i, longitudinal coordinates of the output value of observation z,

MIMO系统递推最小二乘参数估计（本程序针对2入2出系统） 在实际通信系统仿真过程中非常有用-The multiple-input multiple-output (MIMO) system recursive least square parameters estimation (the program into a system for 2 2) In the actual communication system simulation process is very useful
