Surfaces of revolution around z-axis

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.


plot::ZRotate(f, x = xmin .. xmax, <a = amin .. amax>, options)


plot::ZRotate(f, x = xmin..xmax) creates a surface of revolution by rotating the function graph z = f(x) with x ∈ [xmin, xmax] around the z-axis. The slice of the surface parallel to the x-y plane at a point z consists of circles with radii |xi| given by the solutions of f(x) = z.

The range of the rotation can be restricted with the attributes AngleBegin, AngleEnd, AngleRange. The surface of revolution spans over the given range of the rotation angle.

Surfaces of revolution are parametrized surfaces. The first surface parameter is x, the second is the rotation angle. Surfaces of revolution react to most of the graphical attributes that surfaces of type plot::Surface react to. For example, use Mesh and Submesh to control the numerical mesh or use ULinesVisible and VLinesVisible to enable or disable the parameter lines.

Example 1

For plot::ZRotate, the symmetry for a whole revolution is with respect to the x values:

plot(plot::Scene3d(plot::ZRotate(exp(x), x = -1..1)),
     plot::Scene3d(plot::ZRotate(exp(-x), x = -1..1)),
     Layout = Horizontal)

plot(plot::Scene3d(plot::ZRotate(exp(x), x = -1..1,
                                 AngleRange = -a..a, 
                                 a = 0..PI)),
     plot::Scene3d(plot::ZRotate(exp(-x), x = -1..1,
                                 AngleRange = -a..a, 
                                 a = 0..PI)),
     Layout = Horizontal)



The function: an arithmetical expression or a piecewise object in the independent variable x and the animation parameter a. Alternatively, a procedure that accepts 1 input parameter x or 2 input parameters x, a and returns a real numerical value when the input parameters are numerical.

f is equivalent to the attribute Function.


The independent variable: an identifier or an indexed identifier.

x is equivalent to the attribute XName.

xmin .. xmax

The plot range: xmin, xmax must be numerical real values or expressions of the animation parameter a.

xmin .. xmax is equivalent to the attributes XRange, XMin, XMax.


Animation parameter, specified as a = amin..amax, where amin is the initial parameter value, and amax is the final parameter value.
