Inspired by the results that functions preserve orthogonality of full matrices, upper triangular matrices, and symmetric matrices.
We finish the work by finding special orthogonal matrices which satisfy the conditions of preserving orthogonality functions. We give a characterization of functions preserving orthogonality of Hermitian matrices.
