<p>As the optimized 4th order second derivative operators have been proven to cause instabilities, simply call the minimal bandwidth operators regardless of parameter choices.</p>
<p>Note: The 4-2 second derivative operator was the only one to have an optimized variant. I suspect that it was never tested before. This makes the 4-2 second derivative operator behave like the -3 and 8-4 operators.</p>
