How would I generate code for implementing the triangle function triangle(2Bt-n) for n = 1:20
so far:
t = 0:0.005:1;
g_t = 0;
g_a = sin(2*pi*t)+(0.5*cos(6*pi*t))+(0.25*cos(18*pi*t)); %given
B = 10;
for n = 1:20
h = 2*B*t-n;
g_t = g_t + (n/(2*B)).*g_a.*(1-abs(2*B*t-n));
end
figure(1);
hold on;
box on;
plot(t,g_t,'r');
plot(t,g_a,'b');
ylabel('amplitude g(t)');
xlabel('time t');
title('sync waveform reconstruction');
axis([0 1 -2 2]);

How about using sawtooth(), or using triang() followed by repmat()?

Attached is my demo. I've posted it several times before.
