If you have the equation of the plane, then why do you need an interpolation function? I think you need to think a bit about your problem, or at least, explain yourself with far more clarity.

I don't need an interpolation of the plane but I'm searching some function or method that put this point on the plane, but I don't want the project iron of this point in the plain.

I think what John is saying is that if you have an equation for your plane, say, Z(x,y) = 5x + 3y -2, and you have the (x,y) values for a cloud of points, you can put those points on your Z plane by plugging their x and y values into your equation. So plot the plane as a surface, set hold on and then use plot3 to plot your points on the plane.
