The set_param function can be used to set a value such as a gain. Here is an example. The gain value supplied to set_param must be a string, not a number.

for iGain = 1:length(listOfGainValues)
    strGain = num2str(listOfGainValues(iGain)) ; 
    set_param('yourModel/yourBlock/Gain', 'Gain', strGain) ;
    % Run your simulation here with this gain value
end

thanks for your reply.

basically, my question is not about using the gain from code. but its about how can i multiply 's' to the gain(k) in simulink.

Can you please explain? Do you want your GUI to increase the gain prior to simulation, or do you want to add a block that increases the gain by a factor of s during the simulation, or...?
