how about just using stem()?
sig = randi([0 1],20,1);
stem(sig,'markerfacecolor',[0 0 1])

L = 1024;
Periods = 4;
M = 128;
A = 1;
figure,plot( squareWave(L,M,Periods,A) )
function signal = squareWave(L,M,Periods,A)
signal = zeros(L,1); %initialize signal with zeros
if mod(L,Periods) ~= 0
signal = -1; % False input data
end
T = L/Periods; % Get length
% Replace only non-zero values
for idx=1:Periods
signal( 1+(idx-1)*T:1+(idx-1)*T+M) = A;
end
end
