编写一个可以从一幅图像中提取一幅矩形子图像的函数。(Write an image can be extracted from an image of a rectangular sub-functions.)

利用容积卡尔曼滤波器写的一个滤波程序，完美运行(A filtering example that uses the cubature Kalman filter)

用粒子群算法实现图像匹配，图像可以自己更换，建议先用matlab自带图像进行调试(Particle Swarm Optimization with image matching, image Can you change, it is recommended to use own images debug matlab)

matlab程序，有关分岔图，主要是ode45(matlab procedures, the bifurcation diagram, mainly ode45)

此代码为基于遗传算法摩擦模型参数辨识的PID控制MATLAB仿真代码(This code is based on genetic algorithm for parameter identification of friction model simulation of PID control of MATLAB code)

说明：  离散信号Gabor展开的理论及实现颇为繁琐。其中包括离散Gabor变换的标架理论、周期序列的离散Gabor变换、非周期序列的离散Gabor变换以及各种快速算法等。此程序给出给出了一个线性调频信号的Gabor变换。(Gabor expansion of discrete signals and the realization of the theory is quite cumbersome. Including discrete Gabor transform frame theory, the periodic sequence of discrete Gabor transform, non-periodic sequence of discrete Gabor transform and a variety of fast algorithms. This procedure gives a linear FM signal is given the Gabor transform.)

说明：  1、ofdm信道仿真 2、基于梳妆导频的OFDM信道估计 (1, ofdm channel simulation 2, based on the dressing pilot channel estimation of OFDM)

Transformation from ab to dq and dq to ab

元胞自动机沙土模型，matlab仿真代码，非常有参考价值。能成功实现。(The cellular automata sand model matlab simulation code, very valuable reference. Can be successfully realized.)
