I am trying to plot the surface determined by the function x = y(y-2) in 3-dimension. It is a plane perpendicular to xy-plane, and the intersection of this plane and xy-plane is a parabola. In MATLAB, usually we use surf(X, Y, Z) to plot a surface in 3-dimension, where X and Y are vectors with m and n elements respectively, and Z is a m*n matrix which z=f(x,y). However, the surf() is not able to be used here cause z is not a function of x and y. Which command should I use to construct the plane? Thank you very much.

Mary, use
[Y,Z] = meshgrid(-5:5,-5:5);
X = Y.*(Y - 2);
surf(X,Y,Z)
in other words, simply use Y and Z as the independent variables, X = X(Y,Z).
