如何绘制基于像函数f（x，Y，Z）= 0的函数在MATLAB一个三维数字？ [英] How to plot a 3D figure in matlab based on a function like f(x,y,z)=0?

问题描述

如何绘制3D人物 MATLAB 基于像 F（X，Y，Z）= 0 ？ 而这种复杂的功能不能写成 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是一个公知的载体，SV是一个已知矩阵，b是一个已知值。的x，y，z是三个变量。如何得出这样的表面三维方式在MATLAB？

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

我刚刚解决这个问题，从Matlab的文件交换这个工具：
<一href="http://www.mathworks.com/matlabcentral/fileexchange/23623-ezimplot3-implicit-3d-functions-plotter"相对=nofollow> Ezimplot3：隐式3D功能的绘图仪

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