说明：  matlab程序编写的一个8psk的调制程序，里面有一定的注释(matlab programming a 8psk modulation procedures, which have some comments)

数字水印图像的攻击测试 包括滤波、剪切、添加噪声、jepg压缩攻击等等(Attack test digital watermarking images, including filtering, cropping, adding noise, jepg compression attack, etc.)

Demosaicking Algorithm using Bi-linear Interpolation

详细对比了几种小波去噪阈值的选取方法，对实际应用有一定的指导作用(Detailed comparison of several wavelet de-noising threshold selection method, the practical application of the guiding role of certain)

说明：  这个例子显示了如何使用stretchmesh功能 扩大不增加人数的gridpoints在边缘计算窗口的大小。 (This example shows how to use the stretchmesh function to expand the size of the computation window at the edges without increasing the number of gridpoints. )

二维空间高斯混合模型MATLAB代码，以迭代方式逼近得到(Gaussian Mixture Model)

自己编的matlab程序，可以统计深海多金属结核的覆盖率。(Own matlab program, you can count the deep sea polymetallic nodules coverage.)
