MATLAB Matlab: what is the right 3D plotting function for my code?

AI Thread Summary
The discussion centers on 3D plotting in MATLAB, specifically how to visualize a relationship between variables y, O, and x. The user seeks guidance on modifying a loop that calculates y and O for varying x values and wishes to plot these results in a single 3D graph. The recommended approach involves using the meshgrid function to create a grid of x and Omega values, followed by calculating Y based on the formula y = x * Omega^2. The surf function is suggested for creating the 3D surface plot, allowing for a comprehensive visualization of the data.

Hi all, I have a simple question about 3D plotting.

Consider this simple loop, which provides y and O for any x. and I am able to plot y vs O for given x.

for Omega=0:.01:5

y(i)=(x*Omega^2);

O(i)=Omega;

i=i+1;

end

now consider I want to change the value of x, for x=0:.1:3 and plot the group of y's and O's in one plot.(y~O~x) which one of the 3D plot functions are right for this purpose and what will be the code?

I would appreciate you time and help,

Romik

You'll probably want to use meshgrid and surf. Something like:
Code:
x = linspace[/color](0, 3, 100);
omega = linspace[/color](0, 5, 100);
[X Omega] = meshgrid[/color](x, omega);
Y = X .*[/color] Omega .^[/color]2;
surf(X, Y, Omega); [i]% Or whatever order you want to plot...[/i][/color]
