此代码描述的是正弦函数的频谱图,其采样点不同,频谱图的差别(This code is a sine function described in the frequency spectrum, the sampling point is different from the difference spectrum)

求解输入矩阵的阶梯形式，仅供大家学习交流(Input matrix form for solving the ladder, only for them to learn from the exchange)

Double pendulum simulation in Simulink

load frequency control various techniques in Matlab very useful

说明：  ：图像增强是图像处理的一个重要分支，是图像边缘提取、图像分割等的基础．文章介绍了常用的图像增强技 术，并且以Madab为工具完成图像的直方图均衡化、巴特沃斯高通滤波器操作的示例，给出了处理前后的对照图像．重点介 绍了利用小波变换进行图像增强，获得了比较好的增强效果．(: Image enhancement is an important branch of image processing is the image edge extraction, image segmentation, etc. basis. This paper introduces the commonly used image enhancement technology, and to Madab as a tool to complete the image histogram equalization, Butterworth high-pass filter operation of an example is given before and after contrast images. Focuses on image enhancement using wavelet transform to obtain a relatively good enhancement.)

此程序用提升法实现第二代小波变换用的是非整数阶小波变换,采用时域实现,步骤先列后行(procedure used to upgrade Method second generation wavelet transform the non-integer-order wavelet transform, time domain realized, first out go backward steps)

功率补偿仿真图设计，经调试改进，绝对正确(power_compensated)

说明：  基于巴特沃思滤波器的50Hz工频险波器,程序给出了滤波器系数并且作了频谱分析(Butterworth filter based on the frequency of 50Hz- risk devices, procedures given the filter coefficient and made spectrum analysis)
