Newton's method square root
Witrynaunstable. A further variant of Newton's method for the matrix square root, recently proposed in the literature, is shown to be, for practical purposes, numerically stable. 1. Introduction. A square root of an n X n matrix A with complex elements, A E C ,n , is a solution X E CfnXfn of the quadratic matrix equation (1.1) F(X) X2-A = 0. A natural ...

Witryna23 lut 2024 · Using this strategy, we can identify the consecutive roots of an equation if we know any one of its roots. The formula for Newton’s method of finding the roots of a polynomial is as follows: where, x 0 is the initial value. f (x 0) is the function value at the initial value. f' (x 0) is the first derivative of the function value at initial value. Witryna17 sty 2024 · Algorithm. Take a reasonable guess (approximate root) for the square root. Add the approximate root with the original number divided by the approximate root and divide by 2. Continue step 2 until the difference in the approximate root along the iterations is less than the desired value (or precision value).

Of course you cannot expect to use the correct root as the initial guess, otherwise you've already solved the problem.
