Hi all,
I've created a header only library called EigenLab (https://github.com/marcel-goldschen-ohm/EigenLab) which provides run-time parsing/evaluation of matrix math expressions in C++ with a format similar to MATLAB (e.g. in case you need to evaluate a matrix expression input by the user). It can handle variables and uses Eigen for all matrix math operations. Check it out on GitHub and let me know what you think. Also, if anyone knows how I could improve its performance by using Eigen's expression templates, I'd love to hear about it.

Cheers,
Dr. Marcel Goldschen-Ohm

That's a pretty nice project! I added a link to it on our front page (http://eigen.tuxfamily.org/index.php?ti ... sing_Eigen), and I think it should deserve more publicity, so feel free to send an announcement to our mailing list.

Thanks, I will definitely do so.

Cheers,
Dr. Marcel Goldschen-Ohm
