高维非线性数据维数约减，局部线性嵌入算法(Dimension reduction of the higher dimensional nonlinear data，locally linear embedding. )

说明：  Matlab的退火算法的实现，计算一个函数的最小值(Matlab implementation of the annealing algorithm to calculate a function of the minimum)

说明：  自己编的制作红色小球沿一条带封闭路径的下旋螺线运动的实时动画。(their series produced a small red ball with a closed along the path under the rotating spiral movements of real-time animation.)

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,)

对图像进行JPEG压缩编码和解码，用matlab实现(JPEG compression of image encoding and decoding, using matlab implementation)

通过matlab实现从声卡发出不同频率的声波(diffirent frequency sound out)

语音信号处理中，基频特征提取的源程序，实现效果较好(Speech signal processing, baseband Feature Extraction source, to achieve better)

说明：  干涉相位滤波（均值、中值、圆周期）用于insar的三种不同滤波方法(Three different filtering methods for InSAR based on interferometric phase filtering (mean, median and circle period))
