WebAs a full rank matrix, the matrix B should have minimum m independent linear combination column vectors (b i) m×1,1 ≤i ≤y that can be anywhere within the matrix B in a group or individual. Lets assume matrix A is an inverse matrix of non-syestematic non-square binary matrix B with n rows and m columns such A n×m = A 1 The rank of binary matrix will based on the row reduction using boolean operations XOR. Let see the XOR operation: 1 xor 1 =0 1 xor 0= 1 0 xor 0= 0 0 xor 1= 1 Given a binary matrix as A = 1 1 0 0 0 0 1 0 0 0 0 1 0 1 0 0 0 1 We can see the third row equals first row xor with second row.
