Is there a function in matlab that allows you to get the rank of a binary matrix?

I am trying to perform the rank of a binary matrix test to test if a sequence of bits is random. I took a selection of bits from a larger matrix containing all the data and put the data into a sub matrix of 32X32. I was trying to take the rank, but the only function does not take ranks of binary matrices.

When you say "rank" and "binary" do you mean that you are using GF2, e.g., 1+1 becomes 0 ? Or do you mean just that the matrix is of datatype "logical" and you want ordinary rank measurements?

Yes, I mean 1+1 becomes 0.

Before taking the rank, convert your matrix to a numeric type, e.g. double precision

rank(double(YourMatrix))

Perhaps this helps: FEX: parity.
