在一维信号中，用来抑制噪声干扰并保留有用信号，或者对有用信号进行各种变换的数字滤波器有着广泛的应用，在2维中同样的重要，这里面的源代码就是MATLAB经典的线性滤波技术(In one-dimensional signals, used to suppress noise and retain the useful signal, or a variety of useful signal transform digital filter has a wide range of applications, in the 2-dimensional equally important, which is inside the source code of MATLAB classic Linear Filtering Technology)

这个说明倒不是说明函数的功能，只是声明一下函数中出现的问题。 shortest()函数没有问题，在secshortest中我希望只得到一条次短路（或几条roadcost()值相同的次短路），结果却出来好几条，我仔细检查了一下程序，应该没有什么问题。 因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。 有些奇怪 (Note that this is not the function of function, but a statement about the problems in function. shortest () function there is no problem, I hope that in secshortest only a short time (or several roadcost () times the value of the same short-circuit), the result is several out, I carefully examined the process, it should be no problem. Therefore, in use, to be at a short circuit can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest. Some strange)

广义预测控制(GPC)是一种鲁棒性强、能够有效地克服系统滞后、可应用于开环不稳定非最小相位系统的先进控制算法，但由于它需要Diophantine方程计算、矩阵求逆和最小二乘的递推求解，因此计算量很大，本程序针对此缺陷提出四种不基于对象模型且实时性高的广义预测控制快速算法(Generalized Predictive Control)
