在matlab中实现哈夫曼压缩和解压缩。(Huffman compression and decompression in matlab.)

本文分析了SVPWM控制策略的原理，并分析了SVPWM控制策略在三电平逆变器的应用。在理论研究之后，本文采用MATLAB/Simulink仿真软件对上述SVPWM控制策略方法进行了仿真，通过仿真验证了它的正确性。(this paper analyses the theories of NPC three-level inverter and SVPWM.After the studying of theory,this paper simulates the NPC three-level inverter with SVPWM,)

支持向量回归是一种重要的预测技术，通过实现支持向量回归可以预测未来数据(support vector regression is an important prediction technique,we can predict future data by implementing support vector regression )

3D images, image processing so cool

data generation using matlab neural network

本程序实现对图像的增强，通过模糊增强算法，使图像的边缘信息更加明显，图像出来，能够更好的处理高频信息(This procedure to achieve an image enhancement, through the fuzzy enhancement algorithm, so that the edge of the image information more clearly, the image out, better able to deal with high-frequency information)
