说明：  我上传了一本MATLAB遗传算法工具箱及应用，这是一本不错的书，对大家学习遗传算法和熟悉MATLAB工具有很大的帮助作用。(I uploaded a MATLAB genetic algorithm toolbox and its application, this is a good book, for everyone familiar with the study of genetic algorithm and MATLAB tools has a lot of help.)

这是一个虹膜识别检测的程序，只是虹膜识别的功能函数定义(This is a test of iris recognition procedure, only the definition of iris recognition performance function)

说明：  这是一部关于学习Matlab7.0版的编程书籍，比其他版本更详细(This is a version of the program on learning Matlab7.0 books, more than any other version)

This is a image warping tool

设信号 ，用 对x(t)采样得x(n)，是否会发生频谱混叠？现利用FFT分析其频谱。 1．编程绘制该信号的波形。 2．若令N=16，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 3．令N=1024，编程对x(n)做FFT运算，并绘制其幅频特性曲线。 4．分析2、3的运算结果。 设计调试报告要求： 1．工作原理简述； 2．设计思路； 3．难点及解决方法； 4．设计、调试结果及分析； 5．程序文本及操作步骤。(based signal used to x (t) in the sample x (n), whether there will be a spectrum aliasing? FFT analysis is the use of their spectrum. 1. Programming mapping of the signal waveform. 2. If so N = 16, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 3. Order N = 1024, the programming of x (n) do FFT, and the mapping of its amplitude-frequency characteristic curve. 4. Analysis of two, three computational results. Design debugging reporting requirements : 1. Principle outlined; 2. Design; 3. Difficulties and solutions; 4. Design, debugging and analysis of results; 5. Text and operating procedures steps.)
