以循序漸進的方式介紹 MATLab 這種科學程式語言，並透過易懂的範例讓讀者更能快速了解。(MATLab gradual way to introduce this scientific programming language, and through the example of readers better understand quickly understand.)

该本书籍非常适合MATLAB初学者学习，书籍的内容涵盖的面很广，包括对软件的安装，界面的介绍，MATLAB语言，数值计算，程序设计，符号运算，simulink仿真的介绍。这本书的内容，既详细又有许多例子为辅来解释软件的各项功能。对于需要MATLAB作为科研工具的学者们，这是一本非常好的工具书。对于想学习MATLAB软件的同学们，也是一本非常好的学习教材。(This book is ideal for beginners to learn MATLAB, surface content covers a wide range of books, including the introduction of the installation of the software, interface, MATLAB language, numerical computation, program design, symbolic computation, simulink simulation presentation. Contents of this book, there are many examples of both, supplemented by detailed to explain the features of the software. The need for MATLAB as a research tool for scholars, this is a very good tool. For those who want to learn MATLAB software for students, but also a very good learning materials.)

五种常用滤波函数，巴特沃兹低通滤波、中值滤波等(5 different functions of filter)

the fuction performs thresholding to the eye images. this function can be used in implementing daugman algo for iris localization.

Matlab中erf(x)函数的表达式是怎样的，erf(x)与标准正态分布函数之间的关系是怎样的，怎样自己编制一个计算标准正态分布函数数值近似值的函数，如何利用matlab自带的erf(x)函数包近似计算标准正态分布函数的值，数值计算值与用erf(x)转化求得的值之间的相对误差是怎样的。(将中文译成英语 Matlab, erf (x) function expression is what, erf (x) the standard normal distribution function and the relationship between what and how to prepare their own calculation of the standard normal distribution function a value function approximation, how to use matlab comes with erf (x) function package approximate standard normal distribution function values??, numerical values ??and with erf (x) between the values ??obtained into the relative error is like. )

本程序是用于信号频谱分析的实验程序。 主要功能是进行信号的幅值谱计算；同时可完成在选定范围内谱峰的精确频率、幅值和相位计算（计算结果为cos相位）。( This procedure is used to test the program signal spectrum analysis. Main function is to calculate the signal amplitude spectrum the same spectral peaks can be completed within the selected range of precise frequency, amplitude and phase calculation (calculated as cos phase).)
