通过BP网络实现对非线性函数（正弦函数）的逼近。函数比较短，很简练。(Through the BP network for the nonlinear function (sine function) approximation. Function relatively short and very concise.)

猫脸变换用于水印中，将水印图像经过一定次数的变换得到不能识别的图像，增强了水印的鲁棒性(Cat face transform for watermarking, the watermark image after a certain number of times the transform of the image does not recognize and enhance the robustness)

在给定初值和边界的条件下，对偏微分方程组求解( sky_pde_wml0420c , sky_init_wml0420c , sky_bc_wml0420c ， sky_solve_wml0420c )

基于MATLAB的数字水印程序，我不懂大家下着看吧(MATLAB-based digital watermarking process, I do not know how we look forward to the next)

仿真（ZF,ZF-SIC,ZF-OSIC,MMSE,MMSE-SIC,MMSE-OSIC,ML)Vblast接收机的检测性能，绘制误比特率～信噪比曲线(Simulation (ZF, ZF-SIC, ZF-OSIC, MMSE, MMSE-SIC, MMSE-OSIC, ML) detection performance Vblast receiver bit error rate ~ SNR plotted curve)

用matlab直接求解线性方程序，采用直接求解方法的源程序(Directly solving linear equations using matlab program source code using direct methods)

得到可观测到的卫星的坐标后，遍历所有的4个卫星组合（4点定位）计算GDOP。(To obtain the coordinates of the satellite can be observed after traversing all combinations of four satellites (4-point positioning) Calculation GDOP.)

kalman-stack filter for image processing applications

用c编写的矩阵分解程序，对于不用 matlab的人来说，还是有一定用处(Prepared by c matrix factorization procedures, for people who do not have matlab, or there is some use)
