Binary Field Gaussian Elimination for Deriving Generator Matrix G from Input Matrix H

Implementation of binary field Gaussian elimination to obtain generator matrix G corresponding to input matrix H, returning matrix P satisfying mod(G*P', 2)=0 where P' denotes transpose of P. Usage: [P,G]=Gaussian(H,x), where x=1 or 2 (x=1 indicates identity matrix on left side of G). The algorithm performs systematic matrix transformation while preserving all information from H.
