and what is pulse number and how it generates in matlab Adam Danz on 17 May 2021
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)

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]) .

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.
