URL: <http://savannah.gnu.org/bugs/?50734> Summary: initialize newton, steffenson solvers with GSL_FN_FDF_EVAL_F_DF Project: GNU Scientific Library Submitted by: lpsinger Submitted on: Wed 05 Apr 2017 05:36:34 PM UTC Category: Performance Severity: 3 - Normal Operating System: Status: None Assigned to: None Open/Closed: Open Release: Discussion Lock: Any _______________________________________________________ Details: These were the only places in these two solvers where GSL_FN_FDF_EVAL_F or GSL_FN_FDF_EVAL_DF were used independently. If the function or its derivative shared some expensive calculations in common, then this could lead to inefficient initialization of the solver. See attached patch. _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Wed 05 Apr 2017 05:36:34 PM UTC Name: 0001-initialize-newton-steffenson-solvers-with-GSL_FN_FDF.patch Size: 1kB By: lpsinger <http://savannah.gnu.org/bugs/download.php?file_id=40269> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?50734> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
