Update of bug #60797 (project octave): Status: Ready For Test => Patch Submitted Release: 6.2.0 => dev _______________________________________________________ Follow-up Comment #3: The attached patch adds the shortcut for Hermitian matrices along the lines described in comment #2. For performance reasons, I opted to take the square root of the diagonal elements in-place and don't touch the off-diagonal elements of the Schur matrix. Those off-diagonal elements are checked to be below the tolerance. But they might be non-zero. Seems to be working correctly for me.
