离散傅立叶变换程序及希尔伯特变换程序，希尔伯特变换对于信号变换有重要意义。该程序通过验证，效果理想。 (Hilbert transfer program)

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 .)

基于FARIMA的网络自相似业务流模型的研究与仿真 包含三个函数：av.m、far.m、zsrs.m。具体说明见论文及模型说明(Research and simulation of self-similar traffic model based on a FARIMA the network consists of three functions: av.m far.m, zsrs.m. Specific instructions, see papers and model description)

提供了一种inverse gaussian分布定参的程序（程序中离散单位长度为1），R^2是统计量相关系数考虑了未知量的个数和拟合的精度。(Provided an inverse gaussian distribution of a given parameter of the program (in discrete units of length 1), R ^ 2 is a statistic correlation coefficient considering the number of unknowns and fitting accuracy.)
