Another advantage is that geometric properties of the curve are easily determined from a particular level set of the surface . For example, the normal vector for any point on the curve C is given by:

很快的求出各点对之间的最短距离，并且记录路径。(Quickly find out the point to the shortest distance between, and record path.)

主要介绍RLC串并联谐振技术的基本原理，并进行仿真分析(It introduces the basic principles of series and parallel RLC resonance technology, and simulation analysis)

说明：  自适应滤波器的matlab源代码，非常好用，可以实验下(Adaptive filter matlab source code, very easy to use, you can experiment under)

对语音进行的时频分析,语音识别技术作为信息社会朝着智能化和自动化方向发展的关键技术之一，具有重要的研究意义和实用价值。经过近五十年的艰苦探索和研究，语音识别技术研究获得了极大的发展，其中有些比较成熟的技术已经逐步应用于日常生活中。但总体来说，语音识别在研究和实用化方面的难度还比较大。本文概括介绍了语音识别技术的全貌，所采用的关键技术、具体应用以及当前所面临的困难,并对单个语音样本在MATLAB上进行了仿真分析。(right voice for the time-frequency analysis Speech recognition technology as the information society towards automation and intelligent direction of one of the key technologies. The study has important significance and practical value. After nearly 50 years of painstaking study and research, speech recognition technology is a great development, Some of the more mature technologies have gradually applied to daily life. But on the whole, the speech recognition research and the practical difficulty is relatively large. This paper introduces voice recognition technology landscape and the use of key technologies, specific application and the current difficulties faced by, as well as samples in a single voice on the MATLAB simulation analysis.)

matlab插值与拟合，包含了ppt课件以及实例，方便于更好的理解与学习，还有程序代码(The interpolation and fitting_matlab)

主路径信号的前导码，主要包含功能信号和基准时间信号。(The preamble of the main-path signal)

说明：  在cmd介面實做出老鼠走迷宮，可從迷宮逃出(In the cmd interface really make a mouse Maze, escaped from the Maze)
