Comparing BDF vs. Tendler vs. Tischer formulas, #2

1. Runge's function 2. Negative logarithmic error in double precision 3. Negative logarithmic error in quadruple precision 4. Raw results 5. Scripts to generate results In Comparing BDF vs. Tendler vs. Tischer formulas we already compared BDF, Tendler's formulas and Tischer's formulas. There we used the classical Dahlquist test equation $y'=\lambda y$. We repeat the test but with another…
