DCT变换，里面很多有用的matlab程序，你会需要的哈(DCT transform, which a lot of useful matlab program, you will need to Kazakhstan)

粒子滤波的基本仿真程序。设计EKF，UKF，PF 三个算法。已经实现了，还算好用。(Particle filter simulation program. Design of the EKF, UKF, PF algorithm. Has achieved a fairly easy to use.)

用于在3D投影显示中将投影立体图像进行预先的左右翻转。(Inverting the image laterally)

基于MATLAB的仿真环境下的各种实现低通滤波器的方案！我们可以在这个基础上好好的进行研究！(Design FIR filter with firls and remez )

产生服从Gamma分布的噪声可真难啊，呵呵... 产生服从Gamma分布的噪声可真难啊，这个函数费了我好久的力，才理解并实现。写在这里吧。 (Gamma distribution subject to the noise generated can be sad to say ah, huh, huh ... obey the Gamma distribution of the noise generated may be sad to say ah, this function took a long time the power I only understand and implement. Write it here.)
