Hi Matlab Expert,
I would like to know whether a very long polynomial/ transfer function can be simplified into simple equation? Here is the example:

This is unreasonable equation yet it is supposed to be 4th order simple equation. It just shows all the lengthy number which I don't even know how to read. Can you guys come up with function to make this simple to read?
Thank you,
