FFT_TEST

说明：  基于主成分分析实现对特征脸的人脸识别，训练，输出识别率等。(Based on principal component analysis to achieve the characteristics of face recognition, training, recognition rate of the output.)

Apriori implementation in matlab

纹理特征提取的matlab源代码，用灰度共生矩阵做的，最终得到一个8维的纹理特征向量。(Texture feature extraction matlab source code, the GLCM do eventually get an 8-dimensional texture feature vector.)

用牛顿迭代法求方程 f(x)=x³ -x² -1=0 在x。=1.5附近的一个实根。取§=0.000001，取最大迭代数为60. (With Newton iteration equation for f (x) = x ³-x ² -1 = 0 in x. = 1.5 near the root of a real. Take § = 0.000001, take the largest number of 60 iterations.)

高级变换的fft，dft代码实现，包括结果的绘图(fft and dft realization)

介绍了配电网的设备利用率评价指标体系研究(With research equipment utilization evaluation system grid)

说明：  降低ofdm系统峰均比（clipping_slm_pts源码）绝对可以运行 (PAPR reduced OFDM system (clipping_slm_pts source) absolutely can run)

基于patch块的稀疏编码的matlab代码的实现，涉及到基和系数最小化的优化问题(Based on patch block sparse coding matlab code to achieve that relates to the base and the coefficient minimization optimization problem)

对离散序列计算其相关函数，使用基于z变换的离散自相关函数计算(z transformed correlation function calculation.)

this is another gmm training matlab source code. it use k-means for initialization of parameter before trainig, not LBG algirhtm. so it is very helpful for GMM training
