Unable to find Arduino support package in simulink after installation of support package in Matlab

I have installed the support package for arduino in matlab but when the installation completed and i opened the simulink library for finding support package for arduino but there was no such tab of this.Help me to find the arduino in simulink?

neemo - did you install both the support package for MATLAB and the one for Simulink (found here)? Or did you just install the MATLAB support package?
