Can someone please help me out with this code for MATLAB? The g in the vpasolve code isn't making sense to me and I'm getting an error when I run it.

Find the poles and zeros of transfer function in problem 5 by vpasolve" command in MATLAB; present your answers to 4 significant digits. Code example: syms s num s*4+ s3 2*s*2+ 1 temp = vpa solve (g -- 0, s) zeros vpa (temp, 4) % Define s as a symbol. % Transfer function nume rator. % Numerically solve. % Round to 4 significant digits. Repeat for denominator
