This was hinted at above, but … Web30 aug. 2016 · Using first and last is better, but still over-estimates the convergence rates (1.15 and 2.37, FE and AB, respectively). Linear least squares is closer to reality: 1.12 for FE, 2.21 for AB. And lastly, linear least squares but excluding the outliers, we get 1.08 for forward Euler, and 2.03 for Adams-Bashforth.
Web31 jan. 2024 · Percent Change Calculator Method 1 Using the Standard Equation 1 Subtract the original value from the new value. When calculating percent increase, the smaller number is the original (or old) value and the bigger number is the new (or final) value. The opposite is true when calculating percent decrease. Web13 nov. 2015 · You need to evaluate the discretization error on several grids with decreasing h and then use the polynomial fit as [alpha, C] = polyfit (lc, error, 1) where lc is a vector of logarithms of characteristic lengths lc = [log (h1), log (h2), log (h3), ..., log (hn)] and error is a vector of logarithms of corresponding error norms.
