"Witryna2 gru 2016 · This way, you can use MATLAB to tackle derivatives of functions for you. You first need to use the syms command, followed by any variable you want. This tells MATLAB that you are now going to treat this variable as "symbolic" (i.e. not a constant). Let's start with some basics: syms x; y = 2*x^2 + 6*x + 3; dy = diff(y); % Derivative … " - Newton's method matlab code

Steffensen's inequality and Steffensen's iterative numerical method are named after him. When Aitken's process is combined with the fixed point iteration in Newton's method, the result is called Steffensen's acceleration.
