I was trying to print the results from the damp() function to a text file using fprintf, but fprintf doesn't support it.
I would like to be able to maintain that same format that you see in the command window when printing it to a text file as well.
The following is a sample of what I would like to be able to output into a separate txt file
damp(tf(1,[12 16 560 180])

I have no idea. I'm using R2017. I think that I am using the damp(sys). I see two options, one with damp(A,ts) and another with damp(sys), and the one that shows up in command window is damp(sys). Does this answer your question?

evalc() the function to capture the text.

A=evalc('damp(tf(1,[12 16 560 180])');
Note that this will result in a character vector stored in A that will have embedded newline (\n) characters in it, but not embedded carriage returns (\r) .

To get more accurate numbers than what is printed on screen, use [wn, zeta, p] = damp(sys) to get the arrays.
