vision.CascadeObjectDetector is not available in R2011a. It was shipped in R2012a.
Thanks.

Is there any equivalent command for 'CascadeObjectDetector' in computer vision toolbox (version 4.0) matlab 2011? I wanted to detect face of a person from his image. Any suggestions for substitute functions would be appreciated

You might be able to call upon the third-party OpenCV library. In later versions of MATLAB, a specific interface is provided for doing that, but you would need to use loadlibrary()

You might have installed the software, but did you license it?
What does

indicate?
