二元域的高斯消元法求解线性方程组

利用二元域的高斯消元法得到输入矩阵H对应的生成矩阵G，同时返回与G满足mod(G*P ,2)=0的矩阵P，其中P 表示P的转置使用方法：[P，G]=Gaussian(H,x)，x=1 or 2,1表示G的左边为单位阵-binary domain PGE law input matrix corresponding to the formation of H matrix G, Meanwhile the return of mod meet with the G (G * P, 2) = 0 matrix P, which said P P switch home use : [P, G] =
