WitrynaThe Newton-Raphson method uses linear approximation to successively find better approximations to the roots of a real-valued function. The reciprocal of a real number a is defined as a zero of the function: f ( x) = 1 x − a. HDL Coder™ chooses an initial estimate in the range 0 < x 0 < 2 a as this is the domain of convergence for the function. Witryna18 gru 2013 · Dec 18, 2013 at 14:05. @user2906011 That means if you have an equation, say x^2 = 4, then to solve it one would have to pass a function returning x^2-4 because the Newton-Raphson solver finds x such that the function gives 0. If x^2-4=0, then x^2=4, so a solution to the function is a solution to the equation. – Ramchandra …
