Well I think if you want such things eigen (http://eigen.tuxfamily.org/index.php?title=Main_Page) is what you need. However, I would love to see Qt incorporate some basic operations. BUt i'm unable to articulate what those are right now. I think it would get it's tendrils into QImage though, where I do quite a bit of work (image convolutions) _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
