poor vector/matrix-proxy performance Hallo, one of our students looked at the performance of the cholesky decomposition using ublas. The result is quite surprising: $ for i in 100 200 400 800 Posted - Wed Aug 24, 2005 1:26 pm	Gunter Winkler guwi17@... Send Email
restict traits Hallo, matrix_matrix_binary uses restict_traits to identify the type of the iterators. Thus an expression (dense - banded) gives packed_proxy_tag as storage Posted - Fri Jun 24, 2005 8:22 am	Gunter Winkler guwi17@... Send Email
Computing JAJt I wonder what is the most efficient way to compute the product J * A * Jt where J is a sparse matrix, A is diagonal and Jt is the transpost of J. In Ublas Posted - Sun May 22, 2005 7:41 pm	lucaregini Send Email
precondition checks suppressed In the constructor of matrix_range for instance, the precondition checks are commented out. Now there is no error generated when you create a matrix_range that Posted - Thu Mar 10, 2005 12:12 pm	Toon Knapen tknapen Send Email
Unexpected behaviour of project() The following line does not work (it is from a cholesky routine submitted a long time ago on this list): UBLAS::project(U.row (i))(UBLAS::range (i + 1, size)) Posted - Thu Feb 3, 2005 6:45 pm	Antonio Martino vainamonen Send Email
