GM_EM
不错的GM_EM代码。用于聚类分析等方面。( GM_EM- fit a Gaussian mixture model to N points located in n-dimensional
space.
Note: This function requires the Statistical Toolbox and, if you wish to
plot (for k = 2), the function error_ellipse
Elementary usage:
GM_EM(X,k)- fit a GMM to X, where X is N x n and k is the number of
clusters. Algorithm follows steps outlined in Bishop
(2009) Pattern Recognition and Machine Learning , Chapter 9.
Additional inputs:
bn_noise- allow for uniform background noise term ( T or F ,
default T ). If T , relevant classification uses the
(k+1)th cluster
reps- number of repetitions with different initial conditions
(default = 10). Note: only the best fit (in a likelihood sense) is
returned.
max_iters- maximum iteration number for EM algorithm (default = 100)
tol- tolerance value (default = 0.01)
Outputs
idx- classification/labelling of data in X
mu- GM centres)

三维曲线曲面比较演示系统程序设计
设计一个图形用户界面(GUI)演示常见的三维函数图形,至少包含“三维绘图” 、“选项” 、“退出”等菜单,三维绘图的包括:参数方程x=e-t/20cos(t), y= e-t/20sin(t),z=t其中t 为0到2π、参数方程x=t,y=t2,z=t3其中t为0到1之间(在同一图形界面中分别绘制它们的三维曲面和三维曲线图)。“选项”菜单主要包括:网格开关,图例开关,坐标边框开关,色度空间选择菜单,曲线颜色菜单。(Comparison of three-dimensional curves and surfaces demonstration system design to design a graphical user interface (GUI) presentation function common three-dimensional graphics, at least three-dimensional graphics, options , Exit menu, etc., three-dimensional graphics, including: parameters of equation x = et/20cos (t), y = et/20sin (t), z = t one of t from 0 to 2π, parametric equation x = t, y = t2, z = t3 which t is between 0-1 (in the same graphical interface, respectively, three-dimensional mapping of their surface and three-dimensional curves). Options menu includes: grid switches, legend switches, coordinate frame switch, color space selection menu, menu color curve.)
