How to plot the surface of the parabolic cylinder in the first octant bounded by the planes y=4 and z=6?
Y = linspace(0,4,100);
Z=linspace(0,6,100);
surf(Y.^2/8,Y,Z);
I have parametrized the cylinder as , . But unable to plot the desired surface.
Please help to generate the surface

Is it like this?
[X,Y] = meshgrid(0:.5:6);
Y = linspace(0,4,100);
Z=linspace(0,6,100);
surf(Y.^2/8,Y,Z);

y = linspace(0,4) ;
z = linspace(0,6) ;
[Y,Z] = meshgrid(y,z) ;
X = Y.^2/8 ;
surf(X,Y,Z)
