指纹识别的一个小例子，很不错的。 使用matlab编写的，里面一个具体的指纹图片被识别了。(Fingerprint identification of a small example, it is good. Prepared to use matlab, inside a concrete picture of the fingerprint was identified.)

This method will try to extract the centre lines of the veins. This is done by calculating local maximum curvatures in cross-sectional profiles of a vein image. The method is supposed to be robust against varying vein widths and non-uniform brightness.

This function was created as the function getframe() does not capture the data in the required size. This function lets you specify the font size, weight and several other things. * To change of background/font color open the file and make changes at appropriate places, as it is, it puts black text on white background.

包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角，有井曲线作为输入可计算其地震波的衰减,matlab程序运行时导入数据文件作为输入参数。( It comprises aircraft flight attitude control, such as slip angle, tilt angle, roll angle, pitch angle, There is a well attenuation curve as input to calculate its seismic waves, Import data files as input parameters matlab program is running.)

利用大整数问题实现catalan数的求解，catalan数的计算涉及到互质问题(The use of large integer problems solving to achieve catalan number, catalan calculation of the number of issues related to coprime)

power_voltmeasure.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_voltmeasure.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

决策树的ID3算法的源代码，最后是其实验数据，运行很简单！(ID3 decision tree algorithm source code, and finally the experimental data, the run is very simple!)
