Mathematica函数 函数使用介绍和软件使用介绍(Mathematica function function description using the description and software)

这个是霍夫曼编码的问题，要求输入只含有ABCD的四句话，且每句8个字符的长度，然后求出四个字符每个的概率，然后当成权值计算霍夫曼编码，我的这个程序已经实现了输入、概率统计、计算出霍夫曼编码存在了bian[]这个数组中(hoffuman decoding)

The book is an introduction to the application of fault diagnosis and fault toler- ance in the areas of electrical engineering, mechanical and chemical engineering and computer science. It is addressed to students and practicing engineers in research and development, design and manufacturing. Preconditions are basic undergraduate courses in system theory, automatic control, and mechanical and/or electrical engi- neering.

FDM method in Laplace problem

This program is written to compute the navigation position and sensor parameters as well as attitude angles roll-pitch and yaw through Si Error dynamics.

水和蒸汽性质计算V5.5，能够计算任何条件下水和蒸汽的参数，能够在matlab下使用。(Water and steam properties calculation V5.5, able to calculate any conditions of water and steam parameters can be used in matlab.)

用主程序分析法和Matlab编程，对数据进行综合处理，对全国大学生数学建模的参赛者帮助很大(Main program for the analysis of mathematical modeling, mathematical modeling of the National University of great help participants)

fft带阻滤波器，简单实用，最干净的实现数字数据滤波；(fft band stop filter , simple and practical , the cleanest digital data filtering )

可用来求解多仓库的车辆路径问题，经测试可直接运行(This program can be used to solve the vehicle routing problem of multiple warehouses, and can be directly run after testing)

本目录主要包括：文档和两个源代码。 其中一个源代码是识别程序的，另一个是一个矩阵类库的，书里面也使用过，所以一并附上。 因为已经保存了训练好的网络权值，所以第一次使用识别程序时，可以直接运行\Release目录下的可执行文件，然后对图片目录中的测试图片进行读入、识别。 当然读者也可以自行用训练样本训练网络，不过要特别注意训练样本的选择，否则可能造成识别率很低。训练样本选择的原则是，尽可能的有代表性，在训练时间不至于太长的情况下，训练样本数目尽量多。 (This directory includes: documentation and two source code. One of the source code is to identify the procedure, the other is a matrix class library, the book which is also used, so be attached. Have been saved because of the trained network weights, so the first use of identification procedures, he can run Release directory Under the executable file, then the test image directory read pictures, identification. Of course, readers are free to use the training samples to train the network, but pay special attention to training samples, otherwise it may result in knowledge Do not rate very low. Training sample selection principle is that as far as possible, representative, in the long training time Buzhi Yu s case, the training Training sample size as much as possible.)
