潮流计算：算例为IEEE33 计算网络节点电压 (Computing network node voltage power flow calculation examples for the IEEE33)

说明：  可计算地下洞室的围岩稳定问题，模拟地下洞室的开挖、支护过程，介质可以是均质体，也可以是分区变化的非均质体，还可有夹层、节理等。(Calculate the stability of underground rock caverns, underground excavation simulation, supporting the process, the media can be a homogeneous body, you can also change the partition of non-homogeneous body, but also as a layer, joints and so on.)

系统动力学的应用，对研究轨道系统的动力学很重要(dynamic analysis)

本程序仿真了AWGN信道下，采用DS扩频对bpsk信号的影响，扩频码采用walsh码，扩频因子16； 接收端进行rake接收，然后分集合并，比较了三种分集方式对误码率的影响 从图像可以看出在扩频因子较高的情况下，最大比值合并与等增益合并性能相近(This program simulates the AWGN channel, using DS spread spectrum signal for bpsk influence spreading code using walsh code spreading factor 16 Rake receiver receiving end, and diversity combining, diversity compares three methods on the bit error rate of As can be seen from the image in the case of higher spreading factor, the maximum ratio combining and equal gain combining similar performance)

这是另一个matlab的贝叶斯分类器设计，可用作作业用(This is another matlab Bayesian classifier design can be used as operating with)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)
