Hi Andreas, I am still working on other porting problems of our applications and did thus not find the time to finish testing and documentation of the bindings...
Hello, I am new to uBLAS, I hope my question is not completly stupid! I am converting my quantum optics programs from F90 to C++. I make heavy use of...
In the following e-mail: http://lists.boost.org/MailArchives/boost/msg37917.php I found the following comparison of MTL and uBLAS libraries performance. Size...
Hi all, Since the original post was mine, I need to comment on this. 1) The quote is taken out of context. It is not a comparison of MTL and uBLAS libraries...
Hi Andrzej, Some time ago (starting in Dec 2002) there was a discussion about uBLAS performance and its comparision to other libraries including MTL.Sparse and...
Hi Angus, ... Interesting problem Joerg wrote, ... I also tried with boost CVS and a couple of compilers (gcc-3.3.1 gcc-2.95.3 intel linux 7.1). I see the same...
... It's a colloquialism. "use ublas in anger" means that I'm using it for real production code, not just playing with it. ... Good news. Then I'll try the...
Hi Joerg, ... I would think this is unneceassary. The workaround seems fine. The element proxies are already complicated enough for me ! Best, Michael...
... Maybe it's some strange 64 bit problem (the code was tested on a Dec Alpha machine running Debian unstable). No matter, I'll try out the yahoo files ...
Hi Angus, ... real ... I see. ... In this order: - Bug fixes - Compatibility fixes (especially for regression tested platforms) - If there's some motion I'll...
... Ok, I tried out the code in the yahoo files section (ublas_2003_10_30.zip). I'm afraid that the assertion is still triggered on the Dec Alpha. Assembled...
Hi Angus, ... Since the two matrics look to be the same but are not equal it suggests a rounding problem. The first thing I would do is subtract one form the ...
Hi All, Just discovered that compressed vectors are no longer working with VC7. At first I thought it must be related to the element proxy changes, but turns...
Hi again, Not sure why I wrote compressed vector I ment coordinate vector as the test case shows. Problem also shows up in latest boost regression runs so...
... Hi Mattias, I am also working on blas and lapack bindings. I was wondering how you handle workspace. I have written bindings for gees, steqr and a few...

Hi Michael, ... I just copied paste your program and compiled: No errors. I am using the 7.1.3088 with 1.1.4322 Framework. ( Are you using 7.0 or 7.1 ? ) The...
Hi Patrick, Thanks for retesting for me. ... Version 13.00.9466 aka VC7.0 Problem must be very VC7.0 specific. No other compiler (intel or gcc) ha s the...
Hi Micheal, ... Sorry, just because I am always a little bit scared, that it is not working anymore on my System. ... Yep. ... I did not doubt this :-). ...
Hi Mattias, thanks a lot for your files, I will have a look at them and will try to do my first steps with ublas. Until now I have been using a quite old...
... Ok, I dug. Attached is a patch to matrix_assign.hpp from the ublas_2003_10_30.zip snapshot. It simply disables the offending assert and adds lots of...
I've just used ublas::vector as a drop in replacement for my own, naïve 3D vector class Coord. Unix 'size' reports that the resulting code is half the size...
Hi, I use typedef bounded_vector<double, 3> Coord; with bounded_vector defined in vector.hpp. You get the size and speed benefit from using static or auto...
... confirmed with gcc-3.2 and ublas_2003_11_04.zip. The problem is common to all sparse matrix types. Interesting problem ... regards Gunter...

How do I compare two (sparse) matrices? Can it be that there is no comparison operator ( bool operator == ) for matrices or am I blind? Thanks....
