二维码的规范，详细说明了二维码的编码方式和过程(qrcode specification)

Prototype Synthesizer Reconstruct one signal using FFT

用householder变换法求矩阵A的正交分解A=QR (Householder transform matrix A orthogonal decomposition A = QR)

基于神经网络观测器的单关节机械手反演控制。将估计速度代替实际速度，可实现无需实际速度信号检测的控制(Single-joint robot based on neural network observer inversion control. Instead of the actual speed of the estimated velocity can be achieved without the control of the actual speed signal detection)

在实际应用着经常需要求解非线性整数规划或混合规划问题，该领域中的一种常用的算法是分支定界(branch and bound)算法，但是matlab工具箱中没有相关的函数。荷兰Groningen大学的Koert Kuipers编写的的BNB20工具箱可以用来求解一般非线性整数规划问题(In practice, frequent need to solve nonlinear integer programming or mixed programming problem, the area a popular algorithm is the branch and bound (branch and bound) algorithm, but the matlab toolbox functions are not related. Netherlands, Groningen University, prepared the BNB20 Koert Kuipers toolbox can be used to solve general nonlinear integer programming problem)

. This book describes the fundamentals and the MATLAB implementation details of the MPEG algorithm. Several demonstrations using MATLAB® software are presented.

笔者自行编写的Matlab环境下的人脸识别算法小实验， 采用的是经典的PCA算法，主要内容是采用SVD方法提取出象素空间上的 PCA主分量特征，分类算法上仅是基于最小距离分类 (The author of the Matlab environment to prepare the face recognition algorithm under small experiment using classical PCA algorithm, the main contents of SVD method is used to extract pixel space on the PCA principal component features, the only classification algorithm is based on the minimum distance classifier)
