I have the following probabilities: 0.8 for category 1 and 0.2 for category 0. I need to randomly draw a category (0/1) such that the it satisfies the probability distribution. Is there such a thing in matlab? Thanks

You can just use rand.
for nn = 1:1000
drawnum = rand(1);
if( drawnum <= 0.2)
category(nn) = 1;
else
category(nn) = 0;
end
end
