chaotic-simulink

FDTD仿真，点源为硬源，上半部分是玻璃，下半部分是空气，能观察得到电磁波的反射现象。(A source of electric field is defined at the top edge of the spatial domain,(in glass) on the left half, which is a hard sinusoidal source, in that it does not change its value due to interference from external fields i.e in other words,the source is a perfect electric conductor.)

the file consists of image segmentation using otsu threshold and finally counting by using the creating the boundary between of them

说明：  用Gardner算法时钟同步的BPSK的源程序(Gardner algorithm for clock synchronization with the source code BPSK)

to calculate colour invariance

说明：  文件包括非线性方程数值计算时常用的lyapunov程序，以duffing方程为例，进行程序计算，可以稍微修改，计算其他方程。(The file includes the Lyapunov program commonly used in the numerical calculation of nonlinear equations. Taking Duffing equation as an example, the program can be modified slightly to calculate other equations.)

可以直接计算信号的四阶累计量，挺不错的小程序，注意信号必须是非高斯信号哟。(Signals can be directly calculated fourth-order cumulant, very good small procedures, the attention signal must be a non-Gaussian signal yo.)

fm modulation using matlab

矩形检测,基于MATLAB的利用霍夫变换，自己弄的，很实用(rectangular detection)
