simulation-QAM

基于Matlab的FDTD算法，很有参考价值。(Matlab based on the FDTD algorithm, a good reference.)

可视化matlab程序，经过原作者改进版本！(Matlab visualization process, after the author to improve the version!)

对图像进行直方图均衡的matlab程序示例。里面有图像处理前后直方图对比，代码简单易懂。(Histogram equalization)

灰色ＰＩＤ控制matlab仿真程序：主要包括连续、离散系统(gray PID control Matlab simulation program : including continuous, discrete systems)

结构分析软件 abaqus 钢与混凝土本构模型 子程序(Structural analysis software abaqus steel and concrete constitutive model subroutine)

独立盲源信号分析,采用快速独立分量分析的方法(Independent blind signal analysis,Based on fast independent component analysis method)

对金属熔体中粒子服从菲克第一定律反应扩散的模拟，并录像，保存格式.avi(Melt the metal particles obey Fick' s first law of reaction-diffusion simulation, and video, save format. Avi)

说明：  自动转向系统的MATLAB/simulink模型，参数需要自己调试，可以自动跟踪预定的道路(参数请自己调试)(The MATLAB/simulink model of automatic steering system, whose parameters need to be debugged by itself, can automatically track the predetermined road.)

信号去噪的基本步骤： （1）信号的小波分解； （2）小波分解高频系数的阈值量化； （3）信号的小波重构。使用分解的低频系数以及阈值量化后的高频系数进行小波重构。 (The basic steps of signal denoising:( 1) of the wavelet decomposition of signals ( 2) the high frequency coefficients of wavelet decomposition threshold quantization ( 3) the signal wavelet reconstruction. Using the decomposition of the low frequency coefficient and threshold quantization the high-frequency coefficient after wavelet reconstruction.)
