Dear all
When I test the simple code in page (<http://www.mathworks.com/help/vision/ref/showpointcloud.html>) to plot 3D point cloud. I get the message
"Undefined function 'showPointCloud' for input arguments of type 'double'.
Error in test_sphere1 (line 9)
showPointCloud([x(:),y(:),z(:)]);"
Why do I get this, I just use the example code:
close all
clc
clear all
numFaces = 600;
[x,y,z] = sphere(numFaces);
figure;
showPointCloud([x(:),y(:),z(:)]);
title('Sphere with the default color map');
xlabel('X');
ylabel('Y');
zlabel('Z');
Thank you!

I got the exactly same question like "Undefined function 'pointCloud' for input arguments of type 'double'." Have you got your problem solved till now?

What version of MATLAB are you using?
showPointCloud is only available from MATLAB R2014b.
Also as Star mentioned, do you have Computer Vision System Toolbox?

I have tested in R2014b and showPointCloud does work.
If ver('Vision') shows the product installed, it is possible that you do not have it licensed. See what license('test','video_and_image_blockset') returns: it should return 1 if you have the product license. Also try
which -all showPointCloud
if the software is installed but there is no license for it you will probably see a note about no license beside it.
