This example uses a graphics object called the Newell teapot. The vertex, face, and color index data for the teapot are calculated by the teapotData function. Since the teapot is a complex geometric shape, there are a large number of vertices (4608) and faces (3872) returned by the function. [verts, faces, cindex] = teapotGeometry;

There is not much heat to plot in that small data set. You might just visualize it with plot3 () and make the markers somewhat large. If you want to interpolate between the few discrete points, you can use scatteredInterpolant. F = scatteredInterpolant (x,y,z,v) creates a 3-D interpolant of the form v = F(x,y,z).

Plotting a 3D Matrix in MATLAB. To plot a 3D matrix in MATLAB, you can use the `plot3()` function. The `plot3()` function takes a matrix as its first argument and a list of colors as its second argument. For example, the following code plots a 3D matrix of ones: matlab plot3(A, ‘r’); matrix — Each row is an RGB triplet representing the color of one edge. The size of the matrix is numedges(G)-by-3. RGB triplet, hexadecimal color code, or color name — Edges use the specified color.Select a Web Site. Choose a web site to get translated content where available and see local events and offers.
