matlab chapter 2 codes

matlab解决多参数优化问题，已经调通过，可以直接使用。并且目标函数有微分构成。(matlab to solve the multi-parameter optimization problems, have been transferred through, can be used directly. And the objective function differential constitute.)

You can call your own C or Fortran subroutines from MATLAB as if they were built-in functions. MATLAB callable C and Fortran programs are referred to as MEX-files. MEX-files are dynamically linked subroutines that the MATLAB interpreter can automatically load and execute.

多尺度Retinex代码算法，能够很好的是实现边缘锐化和对比度增强。(Multi scale Retinex code algorithm, can very good realize edge sharpening and contrast enhancement.)

高斯脉冲波源下的磁偶极子场的计算，并与fdtd法进行了比较(The analytical solution to the Hertzian Dipole (with a Gaussian pulse source) problem for comparison with the FDTD simulation.)

基于DTW的语音情感识别！运行环境MATLAB!(Speech Emotion Recognition Based on DTW! Operating environment MATLAB!)

Turbo编码技术及其在移动通信中的应用研究(Turbo coding technology and its application in mobile communication research)

说明：  matlab中的kalman滤波工具箱；解压后请置于toolbox目录下，添加addpaht(genpath( 路径 ))。 (of Matlab Toolbox Kalman filtering; please unpacked placed toolbox directory, add addpaht (genpath (path)).)

MATLAB编程，我认为最实用的一部书。的确很详细，从新手到高手。(MATLAB programming, I think it is the most practical one book. Which is very detailed, from the novice to master.)

心音信号的DCT域变换压缩编码，LLoyld最佳量化与霍夫曼编码，利用心电R波进行分帧，在不到1 左右失真度的情况下达到了6.0以上的压缩比(Heart sound signals on DCT transform coding, LLoyld optimal quantization and Huffman coding, the use of ECG R wave sub-frame, less than about 1 in the case of distortion to achieve a compression ratio of more than 6.0)
