Do you have the signal processing toolbox? If so, see sawtooth.
Have you searched the forum for an answer because this question has definitely been addressed.

The super-explicit way:
x = [0 1 1 2 3 3 4 5 5 6 7 7];
y = [0 1 0 0 1 0 0 1 0 0 1 0];
plot(x,y)
You could build those sequences any number of ways. Here's one:
xp = 0:2:7;
x = reshape(xp+[0 1 1].',1,[]);
y = reshape(xp+[0 1 0].',1,[]);
y = mod(y,2);
plot(x,y)
You could also use SPT tools:
x = linspace(0,7,1000);
y = max(sawtooth(pi*(x-1)),0);
plot(x,y)

Ran in:
Another approach using a logical threshold (specific to this waveform) —
t = linspace(0, 7, 500);
s = rem(t,2);
s = s.*(s<1);
figure
plot(t, s, 'LineWidth',2)
grid
axis([0 7.1 0 1.1])
.

but how to give pulse width and pulse period for above sawtooth signal

Two months!
In this instance, pulse width is one-half the period, and the period is the time between peaks. Several functions, such as findpeaks, islocalmax, islocalmin, and others are useful here.
