Please post more details. What exactly does "create" mean here? A 3D visualization? A function which replies random numbers?

rolls = randi(4, 1, 50)
for i=1:50
switch rolls(i)
case 1
Results(i) = {'right'};
case 2
Results(i) = {'left'};
case 3
Results(i) = {'up'};
case 4
Results(i) = {'down'};
end
end

rolls = randi(4, 1, 50)

Sounds like homework, so all three of us gave you the identical hint. And it looks like Mahdiyar gave you a full answer that is what I think you are asking for.

I guess that this is enough:
randi(4, 1, 50)
