How to draw 2D periodic triangular signal

w=1; % signal width
Amp=1; % signal amplitude
tt=-w:w;
y1=Amp-Amp*abs(tt)/w;

figure;
plot(tt,y1)

is this is code is right??

Not yet. That is just one period, not a waveform with multiple periods. Use repmat() to make more of them.

can u rewrite this code using repmat function

Try this:

w=1; % signal width
Amp=1; % signal amplitude
tt=-w:w;
y1=Amp-Amp*abs(tt)/w;
% Replicate this one period 7 times.
tt = -1 : (1 + 6 * length(y1));
y1 = repmat(y1, [1, 7]);
plot(tt, y1, 'LineWidth', 2)
grid on;
