HOG descriptor for object detection

I would like to know if there is an implementation of the HOG descriptor for objects like "cars" and NOT for Human in MATLAB?

But in the case, only for Man, can you direct me to this code and give me such VIEWS to improve the code that will be used for "objects such as cars or motorbikes".

Now in the toolbar of the Vision Vision system there is an extractHOGFeatures function .
