Simulink Help: Troubleshooting Errors with Transfer Function Block

[satyajith]

Hi Everyone..I am the new member of the group...

I have a doubt regarding simulink..In the transfer function block I have the numerator as 1 and coming to denominator I have [I 1.5] where I is varying with time and I have written code for I (as M file) but when I am running the project I am getting an error.. I don't know what to do..

I am sure that many of you know the solution for this (I am new to simulink) Could you please reply me as soon as possible...If you got any doubts please send me a message...
Thank you
