You probably have an older version of MATLAB installed.
Try the following instead:

Check the output of 'ver' command to confirm you have the statistics toolbox.
If not there is always FEX:

Do you have the Statistics Toolbox?
You have to specify the parameter for the distribution, which is the probability of a "success". Here I'll use p = 0.25
pd = makedist('Binomial','N',1,'p',0.25);
x = random(pd,100,1);
If you want the simple case where p = 0.5
x = randi([0 1],100,1);

I am getting an error saying, 'makedist function is not supported'! Is there any other way of doing it without using the statistics toolbox?
