Matlab code for FFT with two cos functions

matlab上的EMD源程序，无需任何调试，可以直接运行，方便好用！(EMD on matlab source, without any debugging, you can run directly, easy to use!)

说明：  speed control BLDC motor

可将输入的RGB图像转化为灰度图像！在Matlab环境下编程实现。(RGB images can be input into a gray-scale image! In the Matlab programming environment.)

PSCAD tutorial,PSCAD入门实例，含多个基础模型DEMO，对于初学者掌握PSCAD的建模非常有用！强烈推荐，网上找不到这么齐全的。(PSCAD tutorial, PSCAD entry instance, the base model with multiple DEMO, very useful for beginners to master PSCAD modeling! Strongly recommended, not online so complete.)

永磁同步电机滑膜观测器估算电机转速。精度比传统观测器精度高。(Estimation of motor speed by permanent magnet synchronous motor. The precision is higher than that of the traditional one)

对于一幅输入图像，将产生一幅输出图像，输出图像的每个像素点的灰度值由输入像素点决定，将感兴趣特征的对比度扩展使之占据可显示灰度级的更大部分。使一输入图像转换为在每一灰度级上都有相同的像素点数，均衡化会减少灰度级数。大多数自然图像由于其灰度值分布集中在较窄的范围之内，引起图像细节不够清楚。采用直方图修正后可使图像的灰度间距拉大或使灰度均匀分布，从而增大了反差，使图像细节清楚，达到增强的目的。(For an input image, will produce an output image, the output image gray value of each pixel from the input pixel decided to expand interest in the contrast of features to make it account for more gray levels can be displayed most. Make an input image is converted to grayscale in each pixel have the same points, equalization will reduce the gray series. Most natural images because of their gray value distribution concentrated in a narrow range, causing the image detail is not clear enough. Make the image histogram revised by the gray space widening or so gray uniform distribution, thereby increasing the contrast between the image details clear objective to achieve enhanced.)

讲解了 MATLAB语言环境下 图像压缩和图像融合方面的基本方法和基于小波变换的图像分解与重构。(Explained the MATLAB language environment, image compression and image integration of the basic methods and wavelet-based image decomposition and reconstruction.)
