matlab-spectrum-estimation

提升函数lwt函数和lsinfo函数的函数功能，语法格式及使用说明，简单易懂(Lwt function and enhance the function function function function lsinfo, grammar format and instructions for use, easy to understand)

FRFT 具体的程序，有关天处理LFM信号的，特别好。(FRFT specific procedure, the days of LFM signal processing, particularly good.)

说明：  分别使用周期图法以及改进的周期法实现谱估计(Using periodogram and improved method to achieve spectrum estimation cycle)

T型尾翼颤振进计算。结合了nastran生成的模态坐标f06文件及气弹计算软件ZAERO。片条法计算非定常气动力里面的定常附加部分。(T-tail flutter ansys, composite of f06 and ZAERO.)

MIMO技术的基本程序包，包含四个子程序，SIDO,SIMO,SISO,MIMO(Vblast),是MIMO初学者的理想进阶资料(MIMO technology, the basic package, includes four subroutines, SIDO, SIMO, SISO, MIMO (Vblast), is ideal for beginners and advanced MIMO data)

说明：  用subplot，imshow，imread，遍历并显示图库文件夹中的人脸图像（用循环）。运行后图像要显示成矩阵模式的，还得产生统一矩阵和均值矩阵。(With a subplot, imshow, imread, traverse and display the Gallery folder of face images (with circulation). After running into the matrix mode to display images, and have to produce unity matrix and the mean matrix.)
