  1. Right-Click on the simulink block.
  2. Select Block Properties
  3. In the properties dialog select Callback tab
  4. Select OpenFun in the callback function list
  5. Write your m-file function call (or script name) in the textbox.
  6. If your m-file is not located in current directory, then set m-file directory in matlab path. You can set the path in "OpenFun" callback also using addpath() command.

Titus is right. 'OpenFun' callback will execute on double mouse click. I think, there is no callback for single mouse click on simulink blocks.

I know, this question was asked quite a while ago, but still the answer might be helpful for whomever.
An easy way to go is using a textblock. Under properties you'll find the 'ClickFcn' which executes on single-click.

mdl=mdlname;
blk=[mdl,'/blkname'];
set_param(blk, 'Selected', 'on')
It will work as single click like selecting the particuler block.
Hope this helps.
