solving for a real root using Brent's method - cdeaglejr - 12-03-2016 03:19 PM
This HP Prime program demonstrates how to interact with a routine named brent which solves for a single real root of a user-defined, one-dimensional nonlinear function coded as y = fx(x) using Brent's numerical method. Here's the output for an example that solves for the root of cosine(x) between 0 and pi. The displayed error is the difference between pi/2 and the value computed by the brent software. brent's root-finding method root = 1.57079632679 error = 0.00000000001 The attached zip file includes a PDF document with additional information about this algorithm. |
