给定X，Y和Z向量生成轮廓 [英] Generate Contour Given X, Y and Z vectors

问题描述

给出3个向量对X，Y和Z，如何生成轮廓?我了解我们需要利用 contour 情节.但事实是，我们需要为此参数传递2x2矩阵，该矩阵大概是与每个X，Y对相对应的Z矩阵.但这意味着在谈论轮廓生成之前，我必须花更多的精力通过首先使用griddata插值来创建这样的矩阵.

Given 3 vector-pair, X, Y and Z, how to generate the contour? I understand that we need to make use of the contour plot. But the thing is that we need to pass in a 2x2 matrix for this argument, which presumably, is a matrix of Z corresponding to each X,Y pair. But this would mean that I have to go extra miles to create such a matrix by using griddata interpolation first before talking about contour generation.

还有其他更简洁的方法吗?

Is there any other more succinct method?

推荐答案

是.使用 Tricontour 工具.它可以在文件交换器上找到(在Matlab Central上).这可以根据您的需要直接进行轮廓处理，而不会强制您使用meshgrid和griddata.

Yes. Use the Tricontour tool. It is found on the file exchange (on Matlab Central.) This does the contouring as you desire directly, without forcing you to use meshgrid and griddata.
