Plotting Systems in Matlab: x_1(t),x_2(t) w/ Complex Equations

[Tom McCurdy]

How would you plot

$$x_1(t)=c_1e^{-t}+c_2*e^{3t}$$
$$x_2(t)=-c_1e^{-t}+c_2*e^{3t}$$

and similar systems in Matlab?

For example if it was complex like:

$$x_1(t)=5*e^{5t}(c_1 cos(4t)+c_2sin(4t))$$
$$x_2(t)=5*e^{5t}((2 c_1+4 c_2) cos(4t)+(4 c_1 - 2 c_2)sin(4t))$$
