how to control a simulink block through mfile?

Hi I have mfile that includes a while loop.I need for every iteration to change the value of a gain block in simulink model, run the simulink model, and call back another value from the simulink to the mfile. Is it possible?

Use set_param fucntion http://www.mathworks.com/help/simulink/slref/set_param.html

To update your simulink model use

set_param(model,'SimulationCommand','Update')
