%% circuit data
z1=2; z2=-2j; z3=4j; z4=2;
vs=12; is=2;
%% loop analysis
A=[z2+z3 -z3 z1;-z3 z4+z3 0;-1 0 1]; %% mesh analysis matrix
S=[-vs;vs;is]; %% source vector
i=inv(A)*S; %% finding loop currents
vo=i(2)*z4 % output voltage
R=abs(vo) % absolute values of v0
theta=phase(vo)*(180/pi);
disp(['vo=',num2str(vo)]); % this is to display the results
disp(['vo=',num2str(R),'/_',num2str(theta)])

%% noddal analysis
A1=[(1/z1)+(1/z2) 0 -(1/z1);(1/z2) (1/z3) ((1/z1)+(1/z4));0 -1 1]
S1=[-is;0;vs]
node_voltages=inv(A1)*S1
