说明：  这是个混沌理论应用中的李雅普诺夫指数源代码，里面的方程是著名的lorenze方程，它可以帮助我们分析混沌的动力学特性，希望对大家有用(This is application of chaos theory in the Lyapunov index of the source code, which the equation is the famous lorenze equation, it can help us analyze chaotic dynamics, we hope to be useful)

多元统计分析中的因子分析的代码，比较简洁(code of factor analysis in multiple statistics analysis)

一个螺旋矩阵程序，当时找了好久才找到 和大家分享啊，一个螺旋矩阵程序，当时找了好久才找到 和大家分享啊。(A spiral matrix program, at that time for a long time to find and share it A spiral matrix program, at that time for a long time to find and share it )

图论程序：图的关联距阵，最小生成树，深度搜索，欧拉图，连通性，权值矩阵等，有GUI(The correlation of the graph, the minimum spanning tree, the depth search, the Euler diagram, the connectivity, the weight matrix, etc., with a GUI)

关于信号处理方面的内容，在matlab编程实现时详细解答(Signal processing on the content of programming in matlab to answer in detail)

快速的2D/3D区域生长算法，通过对邻近像素进行优先级排队进行加速，效果优于matlab本身的区域生长算法(Native Matlab implementations of region growing algorithms are usually quite slow, especially for 3D input data. This submission is a mex implementation of a 3D/2D region growing algorithm. The region growing process is further accellereated by using priority queues for the neighbourhood pixels.)

this function returns the SIFT descriptors DESCR of the SIFT frames P defined on the octave G of the Gaussian scale space.

一种高效的免疫算法，可以被用来进行故障诊断。经过检测，效果较好。(A highly effient immune algorithm and can be used in the fault diagnosis field)

说明：  内容为《MATLAB图形图像》用到的部分程序,希望对大家有帮助!(some examples of the use of matlab)
