我以前主要做MTALAB图像处理工作，现在慢慢整理以前的代码，上述未简单的图像对数变换处理程序(I used to do MTALAB main image processing work, and now slowly finishing the previous code, these are not a simple logarithmic transformation of the image processing)

R/S分析的程序，用来计算Hurst指数用的(R/S analysis procedures used to calculate the index Hurst)

采用模态叠加法和Newmark方法求解悬臂梁的响应，可以直接运行，经验证程序正确(Modal superposition method and Newmark method for solving cantilever response, and can directly run the program properly validated)

采用FCM方法进行脑活动区域检测，该代码具有较好的效果(FCM method using regional brain activity detection, the code has a good effect)

说明：  DSP实验的matlab实现，如 离散时间系统，傅里叶变换，快速傅里叶变换等(dsp FFT)

经PPM调制的超宽带信号经高斯白噪声信道的系统仿真,给出了时域和频域图(Modulated by the PPM UWB signal by Gaussian white noise channel of system simulation, given the time and frequency domain map)

Butterworth high/low and band pass filters are applied to image...

This paper shows how electrical engineering undergraduates can acquire a working knowledge of the finite element method (FEM) within a short period of time using MATLAB. For simplicity, only first-order triangular elements are considered. The scalar wave equation for homogeneous isotropic waveguides is used for introducing the FEM. Simple waveguide problems, including a design problem, are discussed as examples. It is shown how the knowledge acquired can be extended to other electromagnetic problems

基于matlab的二极管钳位三电平仿真，补偿后效果很好(model for NPC APF by matlab)

说明：  飞舞的五角星matlab代码,图片绘制了五角星，且可以在屏幕上任意飞动(Flying pentagram matlab code, pictures to draw a five-pointed star, can be anywhere on the screen and flying)
