如何绘制在MATLAB 4D轮廓线(XYZ-V)? [英] How to plot 4D contour lines (XYZ-V) in MATLAB?
问题描述
我有数据集XYZ为坐标和V的值在每个点(100x4矩阵)。
I have dataset of XYZ as the coordinates and V as the value at each point (100x4 matrix).
我使用补丁绘制三维表面。 (由面及放大器;顶点)
I plot the 3D surface using patch. (by faces & vertices)
我怎么能在三维曲面图V(不Z)的轮廓线!?
How can I plot the contour lines of V (NOT Z) over the 3D surface !?
(该Contour3函数图3D轮廓线Z的,但我需要五的轮廓线)
( The Contour3 function plots 3D contour lines of Z ; But I need contour lines of V. )
Actually I want something like this or this.
感谢十亿的帮助。
嗯,事实上我发现等值面命令正是我想要的。
Well actually I found out that the isosurface command is exactly what I want.
不过,此命令要求V数据是一个3D矩阵。但我V是一个载体。而在它的数据是完全不均匀和不规则。现在这里升起一个新的问题:
However, this command requires the V data to be a 3D matrix. But my V is a vector. And the data in it is completely non-uniform and irregular. Now here rises a new question :
我如何转换这种非均匀向量到一个3D矩阵,因此,它已经准备好与等值面命令一起使用!!?
请帮我这个。
