Random Binary Sequence Generator

I need to generate a Random Binary Sequence of 1x10000 size. Purely Random 1's and 0's.
I had implemented it as follows and it does the job with no complaints.
rand_bin = round(0.75*rand(1,10000));
However, are there any Efficient Implementations for this, probably a specific function which was built for this or something?
Thanks.

I assumed that was what was wanted. Otherwise round(rand(1,10000)) is more efficient.

use randi()
x = randi([0 1],10000,1);

If we want to generate all unique coloums or rows is there a function to do so? any suggestions

Here are two suggestions:
% with 0 <= P <=1
RBS = rand(1,N) < P
% will give roughly a proportion of P ones among N values
% exactly M ones among N values
RBS = false(1,N) ;
RBS(1:M) = true ;
RBS = RBS(randperm(numel(RBS)
Note: I prefer to store the output as logical arrays (true/false = 1/0) that occupy less memory than double arrays.

That's a poor reason to use a one-lined solution ;-)
Long but efficient and readable code is much preferred over short and efficient but unreadable code.
(btw rand(1,N)<P is both short and readable)

This space is not for homework/assignments. Ask a specific question. Explain what you have done for the problem you are facing, then ask the question. There are so many experts here, you will definitely get the answers.
Therefore, I will suggest you to update the question and explain the problem clearly.
