How do I code this to my transfer function ?

I am a beginer in matlab, I just studied it recently and I wonder how to write these equation about transfer function. I understand basic input for the transfer function but I cannot figure out how to type in the e variable and the ^-4 same goes for the 2nd one with the e^-30s

Hi @Jay

To represent time delays in linear systems, you can write something like

G = tf(1,[1 10],'InputDelay', 4)

or

G = tf(1,[1 10],'OutputDelay', 30)

Hey, thanks for the answer. for some reason it doesn't give me the result I wanted, in ended up like this instead of like what the example gives.

Instead of making it 14.49e^-4s it turn it like that. Is it the same? I don't really understand. Thank you!

Can you show what the expected result or response is?

Okay, I've got what you tried to say.

Mathematically, is the same as .

Hope it helps.
