在MATLAB画图技巧与实例(一)中,我们采用plot和plot3函数画散点图。此函数可以控制点的大小、颜色、形状等。 在一般时候已经足够使用,但是在某些特殊情况下,例如在同一数据中,让点的大小和颜色有序变化,此时就需要使用scatter和scatter3函数。 1 scatter函数基本用法 scatter(x,y)scatter(x,y,sz)scatter(x,y,sz,...
在MATLAB中，使用plot、scatter和patch等函数进行绘图时，很多时候都需要使用标记(Marker)对数据点进行标记...
Create a 3-D scatter plot. Use sphere to define vectors x, y, and z. Get figure [X,Y,Z] = sphere(16); x = [0.5*X(:); 0.75*X(:); X(:)]; y = [0.5*Y(:); 0.75*Y(:); Y(:)]; z = [0.5*Z(:); 0.75*Z(:); Z(:)]; scatter3(x,y,z) Vary Marker Size Cop...
Alternatively, specify X, Y, and Z as matrices of equal size. In this case, scatter3 plots the columns of the matrices. For example, plot four data sets. X = [1 3 5 6; 2 4 6 8]; Y = [10 25 45 61; 20 40 60 70]; Z = [12 5 6 8; 9 13 2 7]; scatter3(X,Y,Z)...

I am using 3D scatter command using the following syntax: scatter3(X,Y,Z,S). The marker size is variable in my case where S is a vector. But the marker size is not in scale with the plot axes. How to make the marker size proportional to the axes units?
pythonmatlabplot收敛曲线 MATLAB不但擅长於矩阵相关的数值运算,也适合用在各种科学目视表示(Scientific visualization)。本节将介绍MATLAB基本xy平面及xyz空间的各项绘图命令,包含一维曲线及二维曲面的绘制、列印及存档。 plot是绘制一维曲线的基本函数,但在使用此函数之前,我们需先定义曲线上每一点的x 及y座标。下例可画...
