can't find pointCloud.plot function

[YangYunfang]

hello! I an a newer to deal with point Cloud data in matlab, I attempt to plot point clouds, but the error occured, showing that the class pointCloud didn't have the plot function. I checked the matlab help, it shows that the pointCloud class really own the plot function. Why many reference matlab code use the pointCloud.plot function? Should I download another source of class pintCloud?
