Tiva Launchpad Programming with MATLAB

Dear people,

I have MATLAB 2015b and I am new to embedded system programming with MATLAB. However, I have seen my colleagues working with MATLAB and programming Texas Instrument DSPs. Howeveer, I do not have a DSP now. I have only a EK-TM4C1294XL Tiva Launchpad from TI. I want to program this launchpad in simulink and create some PWMs or control some power electronic equipment with this. This Tiva should have Arm-m4 core and matlab hardware support has an arm m4 package. However, it requires CMSIS and I do not know this program. Could you please tell me how can I program this launchpad if it is possible?

Looking forward to hearing from you. Thank you in advance
