URL: <http://savannah.gnu.org/bugs/?46369> Summary: lmniel nonlinear least squares solver optimization Project: GNU Scientific Library Submitted by: psa Submitted on: Tue 03 Nov 2015 06:51:35 AM GMT Category: None Severity: 3 - Normal Operating System: Status: None Assigned to: None Open/Closed: Open Release: Discussion Lock: Any _______________________________________________________ Details: The lmniel solver is using dgemm to compute J^T J and then a QR decomposition. This should be changed to dsyrk and a Cholesky decomposition for speed improvement _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?46369> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
