i have data in m.file..how to put the data in simulink

hi all. I have basic questions.. I have data like..a=20; b=30; and so on.. then I built my own Simulink which the gain block I just put a/2..b/6 and so on... so my question is how to put the m.file in Simulink.. is it in the model properties?? can someone help me.. because the data... a,b and so on..is changeable..so easy for me to use the m.file instead of changing the value in the gain blocks everytime.

You can use the PreLoadFcn model callback to call your MATLAB file that creates the data. Please see Load Variables When Loading a Model.
