Hi Suppose I have a symmetric matrix defined on the Z2 field {0,1}. I want to calculate its rank. Do we have any function to do this? Thanks

Here is an example using Nemo; first define the field \mathbb{Z}_2: using Nemo Z2 = ResidueRing(ZZ, 2) For purposes of the example, create a random base matrix, e.g. X = rand([0,1], 4,5) or define one: X = [ 0 1 1 0 1 1 0 1 1 0 0 1 1 1 1 0 1 1 0 1 ] then convert it into a …
