How can I draw this waveform, it is a non periodic signal with the intervals like this {[1.54,2.49], [4.97,5.88], [6.69,7.98], [8.05,8.25],[8.58,9.09], [10.48,10.86], [11.16,12.97], [14.51,15.24],[15.38,15.60], [17.20,17.74], [19.16,22.38], [23.69,23.73],[24.59,25.47], [25.59,26.22], [26.65,29.27]}, these intervals are the starting and ending pionts of shaded area.

Try this:
C = {[1.54,2.49], [4.97,5.88], [6.69,7.98], [8.05,8.25],[8.58,9.09], [10.48,10.86], [11.16,12.97], [14.51,15.24],[15.38,15.60], [17.20,17.74], [19.16,22.38], [23.69,23.73],[24.59,25.47], [25.59,26.22], [26.65,29.27]};
figure
hold all
for k = 1:numel(C)
patch([C{k} flip(C{k})], [0 0 1 1], [1 1 1]*0.8, 'EdgeColor','none')
end
hold off
It reproduces the image you posted, so I will not re-post it here.
EDIT — Added pulse train plot.
To draw it as a pulse train:
figure
hold all
for k = 1:numel(C)
plot([[1 1]*C{k}(1) [1 1]*C{k}(2)], [0 1 1 0], 'k')
end
hold off
grid
.

I am still not certain what you want.
Try this:
N = 25; % Number Of Segments
g = rand(1,N);
b = rand(1,N);
C = mat2cell([cumsum(g+b); cumsum(g+b)-b]', ones(1,size(g,2)), 2);
figure
hold all
for k = 1:numel(C)
patch([C{k} flip(C{k})], [0 0 1 1], [1 1 1]*0.8, 'EdgeColor','none')
end
hold off
set(gca,'Layer','top', 'Box','on') % Put Axes On Top Of ‘patch’ Objects
legend('DoS')
figure
hold all
for k = 1:numel(C)
plot([[1 1]*C{k}(1) [1 1]*C{k}(2)], [0 1 1 0], 'k')
end
hold off
grid

I do not understand what you want. The code I wrote is about as simple as I can create it, unless there is information about this that has so far not been posted. The loops are necessary because of the nature of the data. Each interval must be plotted individually in the patch call.
