I would like to represent a transfer function on MATLAB which includes one 1/s term, while the rest of the terms are 0 or positive exponent. Something like:
F=(1/s + s)/(s^2 + s +1).
The tf function can create a transfer function with all 0 or positive exponents, or one with all 0 and negative exponents, but not one which mixes them (as far as I can tell).
Does anyone know a way to represent such a transfer function in MATLAB?
If it helps, I'm hoping to use it with the nyquist function.
