用MUSIC算法和改进的协方差算法实现的功率谱估计(MUSIC algorithm and the modified covariance algorithm of power spectrum estimation)

直方图提取函数，用于人脸识别中，输入一幅图像，函数内部对输入图像做短时傅里叶变换，得到四幅幅度图，再求四幅图的直方图特征，合并后输出(Histogram extraction functions for face recognition, the input image, the input image inside the function to do short-time Fourier transform, the four magnitude diagram, and then seek four graph histogram feature, the combined output)

irst, let s create a simple vector with 9 elements called a.

汽车变速箱的扭震模型。可以用来描述变速器的振动特性，本人自己编写的。(very perferct model of the gear box.)

FMOLS 比OLS更加科学合理，强烈推荐使用(FMOLS )

lqr 控制仿真程序，一般毕业设计要求的，实际上我是上传 来下载的(lqr control simulation program, the general requirements of graduation design, in fact, I upload to download)

卡尔曼滤波程序，对学习很有帮助，希望大家能够一起学习(Very Good)

说明：  Z-N整定 PID整定 SIMULINK模型，参照书上的Z-N整定模型搭建(Z-N tuning PID tuning SIMULINK model, reference book Z-N tuning model)

说明：  定义法求解Lyapunov指数方法，精度比较低。(Index definition methods of Lyapunov method, the accuracy is relatively low.)
