problem in loading data in Stitch point cloud example

Hi there...

i am working with Stitch point cloud example

>> edit StitchPointCloudsExample

i have taken taken 3D point cloud x,y,z coordinate using following code which is also an example in matlab 2016a if you search depthToPointCloud

%Create a System object™ for the Kinect device.
% class is the foundation on which .NET Framework applications, components, and controls are built.
depthDevice = imaq.VideoDevice('kinect',2);
%Warm up the camera.
step(depthDevice);
%Load one frame from the device. The initial frame executes slowly because the object must wake up the device.
depthImage = step(depthDevice);
%Convert the depth image to the point cloud.
xyzPoints = depthToPointCloud(depthImage,depthDevice);
%Render the point cloud with false color. The axis is set to better visualize the point cloud.
pcshow(xyzPoints,'VerticalAxis','y','VerticalAxisDir','down');
xlabel('X (m)');
ylabel('Y (m)');
zlabel('Z (m)');
%Release the System object,
release(depthDevice);

The problem is that when ever i try to load data in this example following error appears

Cell contents reference from a non-cell array object.

Error in map (line 3) ptCloudRef = xyzPoints{1};

map is name of my m file , i have changed renamed StitchPointCloudsExample. xyzPoints is 3d point cloud x,y,x coordinates which i have obtain from above mentioned code and kinect

would anyone help me what i should do after i have obtain 3D point cloud from above mention code and kinect xbox 360. so that am able to get my own 3D map

regards
