Hi, I want my triangle wave to start at the origin, how can I do that?
This is my code:
t = linspace(0,6.840,10000);
x = 19.6.*sawtooth(t,0.5);
plot(t,x)
grid on
xticks([0 1 2 3 4 5 6 6.840])
yticks([-19.6 -15:5:15 19.6])

You can just offset t
t = linspace(0,6.840,10000);
x = 19.6.*sawtooth(t+pi/2,0.5);
plot(t,x)
grid on
xticks([0 1 2 3 4 5 6 6.840])
yticks([-19.6 -15:5:15 19.6])
