All operation are modulo 2. I want to calculate the inverse of a matrix. Is there any easy way to do that? I have tried the usual method of finding determinant and all that.

1Yes, there is an easy way. Can you give your matrix here? Also, read this question. – Dietrich Burde Jan 27 '19 at 11:32

3Finding the determinant is the hard way to find the inverse of a matrix (if the matrix is bigger than $2\times2$). Gaussian elimination is much better, and works just fine modulo 2. – Gerry Myerson Jan 27 '19 at 11:52

@ManoharsinhRana that matrix is not invertible because it has two rows that are identical meaning it's singular. – CyclotomicField Jan 28 '19 at 16:05
