Let me explain, what I'm actually solving.

I'm solving Diffusion-Reaction equation(3D) in spherical coordinates.

I'm solving this equation numerically. So at the end I'm getting

, r, θ, ϕ.

So I want to plot this function

on a sphere(

- plane) instead of

palne

Can anyone help in this regard?

Thanks in advance.

在 MATLAB Online 中打开

r = 1 ;

th = linspace(0,2*pi) ;

phi = linspace(0,pi) ;

[T,P] = meshgrid(th,phi) ;

X = r*cos(T).*sin(P) ;

Y = r*sin(T).*sin(P) ;

Z = r*cos(P) ;

surf(X,Y,Z)

axis equal

But where we plot C?

What do you think: why does the surface of the sphere have different colors ?
