用于光谱波长选择的cars，spa等方法以及定性分析 的PLS-LDA方法(Cars, spa and other methods for spectral wavelength selection and PLS-LDA methods for qualitative analysis are used)

说明：  计算波动率基于garch模型，里面包含了四个数据集，大家可以试一试(Calculate volatility based on GARCH)

这本书的目的是让C蛇贪吃

说明：  粘滞声波频率域有限差分数值模拟 可修改模型(2-D viscoacoustic wave simulations)

这是一个贪吃蛇游戏的源程序，可通过控制蛇身的上下左右移动吃到食物后，蛇身增加，最后可输出成绩(This is a Snake game source code can be up and down by controlling the snake to eat the food and move around, the snake increases, the final output results)

说明：  SVM(支持向量机)参数寻优，用到的方法是交叉验证法。(SVM cross validation parameter optimization)

在matlab平台上，使用多尺度curvelet变换，对SAR图像的相干斑噪声进行抑制， 先将图像进行对数变换，把相干斑乘性噪声转换为加性噪声，然后使用一种有效的阈值去噪方法，很好的抑制了相干斑噪声，效果不错。(On the MATLAB platform, the multiscale curvelet transform is used to suppress the speckle noise of the SAR image. First, transform the image to logarithmic transformation and transform the speckle multiplicative noise into additive noise. Then an effective threshold denoising method is adopted to suppress the speckle noise very well, and the result is good.)
