Hello,

Can anyone of please tell me how 3d coordinates can be generated using a simple equation. I have a equation and through a couple of iterations I would like to create a surface plot in matlab.

Please suggest any books from the board which can help me.

Thank you

hi, Try the following code


//To create the 2D domain:
X=-5:0.1:5;
Y=-5:0.1:5;

[x,y]=meshgrid(x,y);

//The coordinates are ready, type the function
z=x.^2+y.^2;//Or Any function of X

// To plot it, See all the types and choose what suits you
figure;
subplot(2,1,1)
mesh(x,y,z);
title('Using the mesh command');

subplot(2,1,2);
surf(x,y,z);
title('Using the surf command');
