How to plot data on a curved surface.
显示 更早的评论
I wanted to plot the data given in a surface:
The x axis should be curved :
The code I used is:
clc;
clear all;
close all;
a=1;
b=1;
x=-a/2:0.01:a/2;
y=-b/2:0.01:b/2;
for i=1:101
for j=1:101
f(j,i)=cos(pi*x(i)/1)*cos(pi*y(j)/1);
end
end
contourf(x,y,f)
colormap(jet)
I wanted to plot the same value of z but x axis should be curved.

What do you mean by
"x axis should be curved"
?

You mean
a=1;
b=1;
x=-a/2:0.01:a/2;
y=-b/2:0.01:b/2;
[X,Y] = meshgrid(x,y);
F = cos(pi*X/1).*cos(pi*Y/1)
surf(X,Y,F)
?

But what's the sense of it ? Only for optics ?

The image looks like a section from a cylindrical surface. MATLAB can definitely plot a curved surface. But the curved x-axis (projected in 3-D) as desired by @Twinkle C M may imply a non-Euclidean geometry.
