I'm trying to make a phasor diagram for a lab report. I'm really new to MATLAB and this is the first time I've tried this. Our textbook has a MATLAB code that is supposed to make a phasor diagram but I keep getting an error message that I can't seem to resolve, "Expression or statement is incorrect--possibly unbalanced (, {, or [.". The commented lines are what I need to run and the uncommented lines are from my textbook. The parenthesis and brackets are balanced so I'm not sure why I'm getting this message. Could someone please advise me on this?

% V1=1.716924368*exp(-j*80.1137631*pi/180);
% V2=9.8515059*exp(j*-9.8862369*pi/180);
V1=10*exp(-j*45*pi/180)
V2=5*exp(j*30*pi/180)
V=V1+V2
MagV=abs(V);
PhaseV=angle(V);
PhaseVDeg=180*PhaseV/pi;
disp(['V=',num2str(MagV,'%3.4g'),...
    exp(',num2str(PhaseVDeg,'%3.4g'),'j)'])
