如何根据 f(x,y,z)=0 等函数在 matlab 中绘制 3D 图形? [英] How to plot a 3D figure in matlab based on a function like f(x,y,z)=0?

问题描述

如何基于f(x,y,z)=0之类的函数在MATLAB中绘制3D图形?而这个复杂的函数不能写成z = f(x,y).

How to plot a 3D figure in MATLAB based on a function like f(x,y,z)=0? And this complicated function can not be written as z = f(x,y).

f(x,y,z)=sum(a.*exp(sv(:,1)-x).^2+sv(:,2)-y).^2+sv(:,3)-z).^2)-b=0

其中 a 是已知向量，sv 是已知矩阵，b 是已知值.x,y,z 是三个变量.如何在matlab中以3D方式绘制该曲面?

where a is a known vector, sv is a known matrix, b is a known value. x,y,z are three variables. How to draw this surface in 3D way in matlab?

推荐答案

我刚刚通过 Matlab File Exchange 中的这个工具解决了这个问题:
Ezimplot3:隐式3D函数绘图仪

I just solve this question by this tool from the Matlab File Exchange:
