基于MATLAB平台实现利用FFT计算线性卷积(MATLAB-based platform for the realization of the linear convolution calculation using FFT)

pca matlab 人脸识别，靠，怎么上传个文件还这么烦，我倒！我晕！(face recognition pca)

本程序是基于DCT的数字水印算法，包含水印的嵌入，提取过程！(watermarking scheme based on DCT！)

说明：  基于核函数的偏最小二乘算法，先对原矩阵进行核函数非线性变化，再用非线性迭代求解(Kernel-based partial least-squares algorithm, first the original non-linear function of changes in the nuclear matrix, and then non-linear iterative solution)

说明：  matalb的原代码主要用圆管的分析，应该有实用价值。(Dimensional analysis and scaling ：Dimensional analysis is a tool based on the observations )

用改进的星座图扩展法降低OFDM信号峰均功率比(Improved constellation expansion method to reduce the OFDM signal peak to average power ratio)

JPEG 仿真 在Matlab7 上运行，效果最佳(The code of JPEG.If some one want using it,please download。)

Matlab被称为第四代计算机语言，利用其丰富的函数资源，可使编程人员从繁琐的代码中解脱出来。Matlab用更直观、符合人们思维习惯的代码，代替了C和Fortran语言的冗长代码，给用户带来的是最直观、最简介的程序开发环境。(Matlab is called fourth-generation computer language function, programmers can be freed from the tedious code. Matlab with a more intuitive, the code in line with people' s habits of mind, instead of a lengthy code in C and Fortran languages, giving users the most intuitive and Introduction program development environment.)

完整的算术编码的编码和译码程序。结合教材：王育民版的信息论与编码。(Complete arithmetic coding and decoding procedures. The combination of teaching: Wang Yumin s version of the theory of information and coding)

说明：  首先对电网节点优化，再PQ分解法求解系统潮流。(First of all, optimization of the power grid nodes, then PQ decomposition method for calculating the trend.)
