matlabr软件应用的图形图像处理，很专业的教材，事例很多(matlabr graphic image processing software applications, very professional materials, many examples)

matx_processor 是MATLAB基础教程中的源程序(A matrix processor, Matx_Proc() is developed which can be used to process and edit matrices and state space models, and perform various kind of matrix analysis in a visible way. The graphical user interface facilities are extensively used to make such a program very easy and flexible to use)

[X,Y,Z]=cylinder2(x,y,z,r,N,o) 向量X，Y，Z轴定义圆柱面中心线 和矢量r定义圆柱面半径，并已 为的x，y，z的长度相同 N是周围围点的数量。默认值 为N= 100。 Ø 定义了矩阵圆柱generatix（圆圈）椭圆 表面。其内容以0和1之间的值，并适用于 小学和中学的母线轴。值的defeault Ø =的（长（x），2）。 矩阵X，Y，Z轴确定圆柱面，冲浪（的X，Y，Z）的显示器 圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o) Vectors x, y, z define the central line of cylindrical surface and vector r defines the radius of cylindrical surface, and has the same length as x, y, z. N is the number of points around the circumference. The default value is N = 100. Matrix o defines ovality of the generatix (circle) of cylindrical surface. Its elements take values between 0 and 1 and apply to the primary and secondary axis of generatrix. The defeault values are o=ones(length(x),2). Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays the cylindrical surface. )

深度学习工具箱，很多深度学习的源码，可以用于后级开发(deep learning toolbox)

说明：  半监督学习(Semi-Supervised Learning，SSL)是模式识别和机器学习领域研究的重点问题，是监督学习与无监督学习相结合的一种学习方法。半监督学习使用大量的未标记数据，以及同时使用标记数据，来进行模式识别工作。当使用半监督学习时，将会要求尽量少的人员来从事工作，同时，又能够带来比较高的准确性，因此，半监督学习目前正越来越受到人们的重视。(Semi-Supervised Learning (SSL) is a key issue in the field of pattern recognition and machine learning. It is a learning method combining supervised learning with unsupervised learning. Semi-supervised learning uses a large number of unlabeled data, as well as labeled data, for pattern recognition. When using semi-supervised learning, it will require as few people as possible to work, and at the same time, it can bring relatively high accuracy. Therefore, semi-supervised learning is receiving more and more attention.)
