MATLAB: How to create a model using the mdl=LinearModel.fit(X,y)

anovalinear regression

I want to use the mdl=LinearModel.fit(X,y) to create a linear Model in Matlab 2011a but I am getting the following error message:
??? Undefined variable "LinearModel" or class "LinearModel.fit".
I have been told that the code can be used in Matlab 2011a however another contributor said the code can only be used for Matlab 2012a.
Thank you
