说明：  本程序是关于FIR和IIR滤波器的设计现(the procedures of FIR and IIR filter design is)

AUV的建模及其参数整定的Matlab程序，可以复制粘贴到Matlab中(PARAMETER IDENTIFICATION OF ARIES)

关于《GPS基本原理及其matlab实现》一书的程序，有参考价值(About GPS basic principles and its matlab implementation, a Book of procedures, reference value)

说明：  matlab实现BP模型。注释明白直观，使用方便。(Matlab implements BP model. The notes are clear, intuitive and easy to use.)

本matlab程序可用于图象融合等领域，值得看看(The matlab program can be used in areas such as image fusion, it is worth to see)

说明：  该代码是一个基于MATLAB语言编辑的四面体有限元长应变四面体算法，包含一个例子很实用，性能稳定。感谢大家的分享。(This code is a kind of constrain Tetrahedral fem compution on MATLAB。there are total code and an example in cube。It is very practical and stable。thank you for your exchanging。 )

霍夫曼（Huffman）编码算法是满足前缀条件的平均二进制码长最短的编码算法。本文用Matlab语言编程实现了霍夫曼（Huffman）编码,并有详细的word说明(Hoffman (Huffman) coding algorithm is to satisfy the conditions of the average prefix length the shortest binary code coding algorithm. In this paper, Matlab programming language to achieve the Hoffman (Huffman) encoding, and a detailed description of the word)
