how to create a vector for a stimulus?

Hello everyone,
I need help creating a vector based on the stimulus's changing position.
I have a stimulus that moves from the center down and from the center up, randomly every 0.9 seconds (See thinnest line in the image).
This stimulus has an amplitude of 70 centimeters.
How can I create a vector that plots this stimulus?
thanks!

A = 70;
p = 0.5;
t = (0:100)*0.9;
y = zeros(size(t));
state = 0;
for K = 2 : numel(t)
R = rand();
if R > p
y(K) = y(K-1);
elseif state == -1 || state == 1
state = 0;
y(K) = 0;
elseif R > p/2
state = -1;
y(K) = -A;
else
state = 1;
y(K) = A;
end
end
stairs(t, y)
