matlab 常用命令，如：hold on 用于保留当前图形和当前坐标轴属性，后面的图形命令只能在当前存在的坐标轴中增加图形，即设置当前坐标轴属性NexPlot为add，(matlab commonly used commands, such as: hold on to retain the current graphics and the current axes properties, behind the graphics commands only exist in the current axes to add graphics, or set the current axes properties NexPlot for the add,)

Returns the JVM class name within the constant pool context of cls class definition.

自适应的遗传算法以及MATLAB实现，拿去学习吧(Standard genetic algorithms and MATLAB implementations)

在YCbCr通道上，对人的嘴唇的寻找，通过大量数据样本得到的嘴唇颜色区域，效果不错，这个程序只是在静态图片里寻找，对做嘴形识别的人有帮助(Channel in the YCbCr on the lips of people search through a large amount of data samples to be the color of the lip region, the effect is true that this procedure only to find a static picture of the so-shaped mouth to help people identify)
