Webfunction y=non_linear_solve(f,x0,tol) % non_linear_solve solves a nonlinear system of equations using % Newton's method % y=nol_linear_solve(f,x0,tol) solves the non linear set of n equations % f={f1,f2..fn}, where each fi=f(x1,x2...xn)=0 is a function of n % variables. f is a cell array containing the function handles. x0 is a Web2 Answers. Newton's method is, provided an initial guess x 0 to f ( x) = 0, you just iterate x n + 1 = x n − f ( x n) f ′ ( x n). In higher dimensions, there is a straightforward analog. So in your case, define. f ( [ x y]) = [ f 1 ( x, y) f 2 ( x, y)] = [ sin ( 3 x) + sin ( 3 y) sin ( 5 x) + sin ( 5 y)] so you throw in a vector of size two ...
