Which of the following Matlab scripts creates a symmetric matrix A. Remember, a symmetric matrix is one that equals its transpose. Use matlab to verify. The way you verify is by creating the matrix and then take the norm of the difference of the matrix and its transpose i.e. norm(A-A'). If this norm is a tiny number then it is symmetric. O a. S=rand(30); A=(eye(30)+5)*(eye(30)+S)'; b. S=rand(30); A=(eye(30)+5)*(eye(30)-S); O C. S=rand(30); A=(eye(30)-5)*(eye(30)+S)^-1; O d. S=rand(30); A=(eye(30) +S)*(eye(30)-S)'; O e. S=rand(30); A=(eye(30)-5)*(eye(30)+S)
