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...

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...

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...
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...
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))...
Hi all, I would like to inform you that a new mailinglist has been created that is dedicated to Generic Linear Algebra Software (GLAS). The aim of the glas-ml...

Hi, I just upgraded my boost install from 1.31 to 1.32 and tried to simply plug the bindings from the sandbox into the 1.32 tree, hoping all would be good. But...
I use lu_factorize() (the pivoting version) and it still seems to be broken as well. The break seems to be in the project() function. I'm using VC++ 7.1. ...
... Could you be more specific. I don't see what is broken actually? I ran the regression tests succesfully and we are using it in other internal projects? ...
Toon, Karl, This is most relevant to you. To me it look like the CVS HEAD is still broken. Karl's vector_temporary deduction seems only to be half implemented....
Toon, I just noticed the thread was/is actually being sent to the old yahoogroups list. I guess we need to be careful to post to lists.boost.org Michael...
Toon, ... I guess I need to start working through some of Karl issue and bug reports for uBLAS_pure! I am programming every day (work!) at the moment so this...
I just performed the merge (I polled about this a few weeks ago and since there were no (negative) reactions ..) The uBLAS_pure branch contained a lot of...
