Kaw, Autar Kalu, Egwu (2008), Numerical Methods with Applications (1st ed.).Comparison between Secant, Modified Secant, and Improved Secant Methods.^ Papakonstantinou, J., The Historical Development of the Secant Method in 1-D, retrieved.Here is an implementation in the MATLAB language (from calculation, we expect that the iteration converges at x = 24.7386): (x) x^2 - 612 The secant method is applied to find a root of the function f( x) = x 2 − 612. In the graph, the x intercept of the secant line seems to be a good approximation of the root of f. Explanation of the code: Manas SharmaPhD researcher at Friedrich-Schiller University Jena, Germany. The following graph shows the function f in red and the last secant line in bold blue.

Generalizationsīroyden’s method is a generalization of the secant method to more than one dimension. A special case of this formula, for n 2 gives as a result square root. If, however, we consider parallel processing for the evaluation of the derivative, Newton’s method proves its worth, being faster in time, though still spending more steps. Numerical Methods in Computational Engineering. a nonlinear equation, bracketing, bisection, secant, and Newton-Raphson methods. This result only holds under some technical conditions, namely that takes as much time as evaluating its derivative and we neglect all other costs, we can do two steps of the secant method (decreasing the logarithm of the error by a factor φ 2 ≈ 2.6) for the same cost as one step of Newton’s method (decreasing the logarithm of the error by a factor 2), so the secant method is faster. Introduction to numerical methods and fortran programming 1st edition. In particular, the convergence is superlinear, but not quite quadratic.
