I want to export the trasfer function of a simple simulink program to the workspace. I know it can be done simply by using the commands
[a,b,c,d]=linmod('model')
sys=ss(a,b,c,d);
tf(sys)
Is there any way to avoid the linmod command? The reason I need to do this is to present this method for people who are not familiar with state-sspace models.

Your model name is transfer, and you have two transfer function named Transfer Fcn and Transfer Fcn1
To get the parameters of Transfer Fcn block
num=get_param('transfer/Transfer Fcn','Numerator');
den=get_param('transfer/Transfer Fcn','Denominator');
model=tf(str2num(num),str2num(den))
