simulation

基于MATLAB的短时傅里叶变换（STFT）的语谱图的画法，MATLAB环境下(MATLAB-based short-time Fourier transform (STFT) of the spectrogram of the painting, MATLAB environment)

对图像进行边缘检测，很简单的一个程序，对初学者很有用！(it detects the edge of the image,a very simple example and it is very useful for the beginner.)

实现Fast visiblity restoration算法(realize the algorithm of Fast visiblity restoration)

可以使用在代码和函数，用于matlab时频分析工具，很好在对初学者有益(You can use the code and function, frequency analysis tool for matlab, the well in good for beginners)

永磁同步电机的MATLAB模型,Clark变换，park变换仿真，及其逆变换 同步旋转坐标系下的数学建模 精致坐标下的数学建模(MATLAB model, Clark transform, park transform simulation and inverse transformation of permanent magnet synchronous motor (PMSM). Mathematical modeling in synchronous rotating coordinate system Mathematical modeling in refined coordinates)

关于数字通信中DFT和FFT的仿真程序，真正有用(On DFT and FFT digital communication simulation program, really useful)

此源码程序是自适应滤波中的自适应均衡器在MATLAB中对其就行了仿真，是自适应滤波的一种应用(The source process is adaptive filtering in the adaptive equalizer in MATLAB on the line in their simulation is a kind of adaptive filtering applications)

多个脉冲积累后可以有效地提高信噪比，中频积累时要求信号间有严格的相位关系，即信号时相参的，所以称为相参积累。(Multiple pulse accumulation can effectively improve SNR, if integration requires strict phase relationship between signals, whereby the signal coherent, so called coherent accumulation.)

work in matlab, iris detection

order to be able to do whatever we want with the given dynamic system under control input, the system must be controllable
