Hi,
I have a plane obtained via regression. Let's say this is z = 2x + 3y + 4. I want to plot this plane AND the data points. How do I do this?

Run the following code:
[x y] = meshgrid(-10:1:10);
z = 2.*x + 3.*y + 4;
surf(x,y,z);
To add the data you can add the following lines:
hold on;
plot3(DataX, DataY, DataZ);
You can check the meshgrid and surf function in the following links:
