有损图像压缩的matlab程序实现，通过dct变换，霍夫曼编码，译码，比较压缩后图像与原图。(lossy image compression)

总体经验模态分解（EEMD）的程序，适合初学者学习。(Overall empirical mode decomposition (EEMD) procedures, suitable for beginners to learn.)

：为了提升自动控制原理课程的教学质量，改善解决课程中计算复杂、公式繁杂、难以理解等问题，我们将Matlab 仿 真技术运用于这门课程中，这款软件有助于提高学生的主动性和兴趣，促进学生分析理解问题和解决问题的能力。文章 主要介绍了Matlab 的概述和特点，Matlab 仿真技术在自动控制原理课程教学中的应用和实例等内容。(: In order to improve the quality of teaching automatic control theory courses, courses to improve the computational complexity of solving the formula complicated, difficult to understand and so on, we will Matlab simulation technology used in this course, this software helps improve students' initiative and interest, promote students' ability to analyze and understand the problem and solve the problem. The article describes an overview of the content and features of Matlab, Matlab simulation technology in teaching automatic control theory and examples of applications and so on.)

快速傅里叶变换 它的主要功能是用fft变换然后识别文字(FFT ,it is used to fft and recogonize chinese )

基于距离角度解耦的MIMO-OFDM雷达波束形成及优化。首先，MIMO-OFDM雷达和OFDM-MIMO雷达的定义在不同的期刊是不同的。这里MIMO-OFDM雷达的定义同IET期刊(见参考文献)，即发射阵列应用频率分集。发射阵列使用频率分集能提高目标检测性能，但是发射波束具有距离角度耦合，波束形成需要解除距离角度耦合。以距离角度耦合效应为目标函数，使用遗传算法计算目标函数最小时的发射载频组合。(Beamforming based on range-angle decoupling of MIMO-OFDM radar. the definition of MIMO-OFDM radar and OFDM-MIMO radar in different journal are different. the MIMO-OFDM radar is equal to IET journal, that is transmitting end is frequency diverse array. Using frequency diversity improve target detective performance, but beanpattern is range-angle coupling, which have an effect on beamforming.)

对图像进行预处理，然后进行经典的阈值分割，形态学分割以及种子区域生长。(Preprocess the image, and then the classic threshold segmentation, morphological segmentation as well as seed region growing.)

基于块对角矩阵的仿真程序，内附注解，非常详细(Block diagonal matrix based simulation program, containing notes, very detailed)
