syms I_1(t) I_2(t)
ode1 = diff(I_1) == ((12*exp(60*1i*t))-(10*I_1)-(0.9*I_2))/0.1;
ode2 = diff(I_2) == ((-0.9*I_1)-(10*I_2))/10;
odes = [ode1; ode2];
S = dsolve(odes);
I_1Sol(t) = S.I_1;
I_2Sol(t) = S.I_2;
[I_1Sol(t), I_2Sol(t)] = dsolve(odes);
cond1 = I_1(0) == 0;
cond2 = I_2(0) == 1;
conds = [cond1; cond2];
[I_1Sol(t), I_2Sol(t)] = dsolve(odes,conds);
fplot(I_1Sol)
hold on
fplot(I_2Sol)
grid on
legend('I_1Sol','I_2Sol','Location','best')

Use the real function.
fplot(real(I_1Sol))
Does this give the expected plot?
