How to plot data on a curved surface.

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"

?

Please see this figure attached

Answer 2

[Torsten]

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)

?

I want the x axis to be curved with some radius and plot the same data

[Torsten]

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

it is for plotting data on curved surfaces

@Torsten

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.
