I have MATLAB R2015a and the command faceDetector = vision.CascadeObjectDetector(); does not work in it. I do have the computer vision toolbox. The error display says Undefined variable "vision" or class "vision.CascadeObjectDetector".

Do you have the Computer Vision System Toolbox installed?

Do you see Computer Vision System Toolbox among the installed products?
