给定一个样本集exset，样本数为M，每个样本点是N维向量，对于给定目标点d，d也为N维向量，要从exset中找出与d距离最近的k个点(k<=N)(knn code c++)

地球物理中的一维波动方程的差分逼近，文档中有原理，源码以及运行结果，非常适合学习文档。(Geophysical differential wave equation in the approximation of a document in principle, source code and operating results, is very suitable to study the document.)

平均误码率统计的的matlab程序，使用的时候还有一点注意事项，见程序内部说明(The average bit error rate statistics matlab program, when used, also Note, see the procedures for internal instructions)

针对变压器的故障诊断，通过概率神经网络对其进行分类。运行程序后，网络输出值和实际值非常接近，很好的实现了对变压器的故障分类。(For the transformer fault diagnosis, we use the probability neural network to classify it. After running the program, the network output value and the actual value is very close, which achieves the good classification of transformer fault .)
