一个用matlab实现的ARMA变换程序

说明：  实现最陡下降法,研究步长因子和特征扩散度对收敛速度的影响(Achieve the steepest descent method to study the characteristics of step length factor and the proliferation of degree of influence on the convergence rate)

femto是目前解决中心基站服务量大、性能低的一个热点方式，该方式可以提供弱信号地方好的通信质量，本代码就同频防干扰做出设计，希望对读者有用-Centre for Settlement of femto base station is the service volume, low performance is a hot way, the way to where weak signals can provide good communication quality, the code to make the same frequency anti-interference design, hope to be useful reader

自己写的matlab里面的，B样条基函数的简单程序，用的是卷积的方法(bspline basic functions,you can use it to conquer some ans)

最大似然估计算法Matlab实现，不容易啊！！！！！！！！！！(Maximum likelihood estimate，not so esay！！！！！！！！！！)

说明：  此程序是变型PID控制算法的仿真程序，采用了变速积分方法，系统偏差大时，积分作用应减小，反之应加强。变速积分可以根据系统误差大小改变积分速度，提高了系统品质。(this procedure is a change in the PID control algorithm simulation program using the variable integration method, the system deviation, the integral role should be reduced, on the contrary should be strengthened. Integral variable speed system error can change the size of integration of speed, quality of the system.)

魔方还原程序,主函数为Cube,采用CFOP，还原步骤为88步左右，底面十字未优化；采用留个3*3矩阵，前面为froo（数字3），后面为baa（数字-3），左面为leff（数字-2），右面为rigg（数字2），上面为upp（数字0），下面为doo（数字1），(Cube restore process, the main function of Cube, using CFOP, the reduction step is 88 steps or so, the bottom cross unoptimized adopt leave a 3* 3 matrix, in front of froo (figure 3), followed by the baa (figure-3), left the leff (digital-2), the right of rigg (figure 2), at the upp (number 0), following the doo (figure 1),)
