Research
by Benoit Jacob on Sunday 20/Jan/2008, @00:39

Thanks for mentioning the "research" aspect of some KDE subprojects. I sometimes think that Eigen is also a research effort i.e. it's the "math department of KDE", especially as a large part of the time invested in it is used in "thinking its design" not actual coding.

indeed; and this is really what makes a reasonable length presentation on "KDE" so rediculous to do: i can only cover so much. that i didn't cover eigen or the cooler features of kalzium, pigment, etc... man.. it just sucks.

all you kde people do way more cool stuff than i can talk about. but don't let that stop you ;)

btw, the last kde4 presentation i did before this one, i actually did fit in eigen and kalzium. =)

Hi Aaron, no problem at all, I was absolutely not expecting or hoping Eigen to be mentioned in one of the presentations (but I'm pleased it was in your previous presentation), in fact the current stable Eigen, 1.0, is a very little thing and is not much used (outside of Kalzium/Avogadro, only a little bit in Krita and KSpread) but I hope that Eigen 2.0, which is a rewrite from scratch, will be much more useful.

I'd like to say thanks for making the whole KDE4 project so inspiring to contribute for.

I've read quickly your blog about Eigen2 and as I don't know how to program C++, I'm not sure I understand how it works.
I understood that you implemented your library in such a way to allow calculation by explicitely writing explicitely something like :

a = c + d;
or
a = c * d;

a,b and c being matrices.
Am i right?
