Plane Perpendicualr to an axis

Hey, how do I plot plane ortogonal to an an axis, in a 3D system.

For example, a plane that is defined by .

Not sure what you mean by "get a plane". The equation you have written, x = 3/2, defines a 3D plane that is orthogonal to the x-axis. What else do you need? What are you doing with this downstream in your code?

[Manuel Ferreira]

basically this is what I want to do. Hope I made it clearer.

You want to graph a 3D plane superimposed on top of another image/plot? Take a slice of that plane through the other image/plot? Or ...?

I want to graph a plane on top of that plot

Hi Manuel,

Given below is a sample code to plot a plane in 3-D defined at ,

[y z] = meshgrid(-1:0.1:1);
x = 3/2*ones(size(y));
surf(x,y,z)

You may superimpose this plane onto any other surface plot using hold on. To adjust the transparency of the plane appropriately set the alpha value after the surf command. Hope this helps!
