URL: <http://savannah.gnu.org/bugs/?49465> Summary: initialize newton and steffenson solvers with GSL_FN_FDF_EVAL_F_DF Project: GNU Scientific Library Submitted by: lpsinger Submitted on: Fri 28 Oct 2016 08:15:20 AM GMT Category: Performance Severity: 3 - Normal Operating System: Status: None Assigned to: None Open/Closed: Open Release: Discussion Lock: Any _______________________________________________________ Details: The attached patch causes the Newton and Steffenson one-dimensional root finders to initialize using GSL_FN_FDF_EVAL_F_DF rather than GSL_FN_FDF_EVAL_F and GSL_FN_FDF_EVAL_DF. This should result in faster initialization for problems where the function and derivative are expensive to evaluate and involve redundant calculations. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Fri 28 Oct 2016 08:15:20 AM GMT Name: 0001-initialize-newton-steffenson-solvers-with-GSL_FN_FDF.patch Size: 1kB By: lpsinger <http://savannah.gnu.org/bugs/download.php?file_id=38826> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?49465> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
