Returns a symmetric matrix
symmetric(A)
Returns a matrix where the diagonal elements and the elements above the diagonal are identical to the corresponding elements of matrix A and where the elements below the diagonal are set equal to the elements above the diagonal of A, i.e.,
B := symmetric(A) -> B[i,j] := A[i,j], if i ≤ j, B[i,j] := A[j,i], if i > j.
