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
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?
