该算法的功能是利用避圈法来求有权图的最小生成树
在函数的编写过程中用到了自己编写的 wode_setdiff(A,b) 函数,具体详参该函数
该算法的实用性相当强,可以实用于任何的赋权有向图最小生成树的求解!!!经过多次不同的运行,
程序的结果都正确无误!(the function is...)

multipath_test
该程序是自己编写的,是基于matlab的多径信道的建立。该多径信道是基于电力线信道特性而构建的,其中的衰落系数是通过阅读大量文献而得到的。该程序能够顺利运行,并画出了信道的各个参数图。(The program is written by myself,which is to build a multi-path channel matlab based. The multi-path channel is based on the characteristics of the power line channel constructed, which is fading coefficients obtained by reading a lot of literature. The program can run smoothly, and draw a diagram of each parameter channel.)

dmctutorial
Dynamic Matrix Control Tutorial
Dynamic Matrix Control (DMC) was the first Model Predictive Control (MPC)
algorithm introduced in early 1980s. Nowadays, DMC is available in almost
all commercial industrial distributed control systems and process
simulation software packages. This tutorial intends to explain the
features of DMC using the dmc function developed by the author.
