Error Undefined Function or Variable 'Sample'

Hi All- i am a matlab noobie for my masters program and am getting an error the first time running this code on my home machine that worked fine in the school computer lab. I am wondering if anyone can help me figure out why? It seems my version of matlab is missing the 'sample' function, whereas it suggests to use 'datasample' or 'randsample' but the way I wrote the code in class it is not working.

Anyone out there that can help?

vote_rate1 = 25;
vote_rate2 = 100;
candidates = [1;0];
vote_prob = [.52;.48];
for trial = 1:1000000
    vote1 = sample(candidates,vote_rate1,vote_prob);
    vote2 = sample(candidates,vote_rate2,vote_prob);
    y(trial) = proportion(vote1==0);
    z(trial) = proportion(vote2==0);
end

sum(y(:) > 0.5)/1000000
sum(z(:) > 0.5)/1000000

You will need to get the code for the sample( ) function from your lab computer.

You must have sample defined somewhere at home but not at school. On your home system, put this code in before you refer to sample:

which -all sample

What does it show in the command window, and how is it different than what you see at school?
