Witryna56 LECTURE 13. NONLINEAR SYSTEMS - NEWTON’S METHOD Save this program as myfsolve.m and run it. You will see that the internal Matlab solving command fsolve approximates the solution, but only to about 7 decimal places. While that would be close enough for most applications, one would expect that we could do better on such a … Witryna5 sie 2014 · By running this code using the exact same parameters as above, we get: f = @ (x) sin (x); r = mynewton (f, 2, 5) r = 2.0000 4.1850 2.4679 3.2662 3.1409 3.1416. Each value in r tells you the guess of the root at that particular iteration. The first element of the array is the initial guess (of course).

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 …
