Merge growth and decay plots

I'm trying to figure out how to merge 2 plot into one continuous plot. I have plotted the exponential growth for a capacitor charging and I have plotted the exponential decay of the capacitor discharging. I can't figure out how to combine both into one continuous plot. Here are my individual codes. First is the growth followed by the decay.

Growth

t1=0:0.0001:5*tau;

v=5;

r=10e3;

c=10e-7;

tau = r.*c;

v1=((0-v).*exp(-t1/tau))+v;

hold on

plot(t1,v1)

hold on

grid on

title('Capacitor Charging')

xlabel('Time (s)')

ylabel('Voltage across capacitor (V)')

Decay

t2=0:0.0001:5*tau;

v=5;

r=10e3;

c=10e-7;

tau = r.*c;

v2=v.*exp((-t2/tau));

hold on

plot(t2,v2)

hold on

grid on

title('Capacitor Discharge')

xlabel('Time (s)')

ylabel('Voltage across capacitor (V)')

I've tried using heaviside but I haven't had any success. Maybe I'm using heaviside wrong. The following will run but only the growth portion shows up on the graph. Can anyone point out what I'm doing wrong please? I'd really appreciate the help.

t1=0:0.0001:5*tau;

t2=((5*tau)+0.0001):0.0001:5*tau;

v=5;

r=10e3;

c=10e-7;

tau = r.*c;

v1=((0-v).*exp(-t1/tau))+v;

hold on

v2=v.*exp((-1/tau).*heaviside(t2-10*tau));

hold on

t=[t1,t2];

vf=[v1,v2];

plot(t,vf)

Try this:

figure
plot(t1, v1)
hold on
plot(t1(end)+t2, v2)
hold off
grid
legend('Charge', 'Discharge')
xlabel('Time (s)')
ylabel('Voltage across capacitor (V)')

Thank you very much!
