simmethod

A short code used to know the frecuency to sintonize a sistem using a PID control

基于MATLAB的圆检测的图像处理，用到了最小二乘法，和霍夫变换(circle detection)

c++ and matlab 散射电流可视化、球体(c++ and matlabScattering current visualization, sphere )

matlab使用的图论中的最小生成树计算(minimum spanning tree)

说明：  由传递函数求伯德图、奈奎斯特图以及Gm、gama、wcg、wcp等，并绘图(The Bode diagram, Nyquist diagram, GM, Gama, WCG, WCP, etc. are obtained from the transfer function and plotted)

用正交调制方法实现模拟调制，包括AM,DSB,SSB,LSB,FM,AM-FM等，实现后，显示时域波形和功率谱密度(Orthogonal modulation method used for analog modulation, including AM, DSB, SSB, LSB, FM, AM-FM, etc., we can show the time-domain waveform and power spectral density)

recognition system for speaker identification

说明：  给出正弦加噪函数，通过FFT,DTFT,做频谱变化，幅度谱和相位谱。(Sine plus noise function is given by FFT, DTFT, make changes in the spectrum, amplitude spectrum and phase spectrum.)

model reference adaptive control using lyapunov method simulation

使用Sobel算子、Laplacian算子对图像进行锐化(Using the Sobel operator, Laplacian operator for image sharpening)
