# LMI (Linear Matrix Inequalities)

Hello.

I installed SAGE and I was very happy with the results it gave in the very beginning.

However, the reason I installed it was because I need an open-source alternative for solving Linear matrix inequalities (LMIs). I did not find an LMI solver in SAGE, though.

I will be very delighted if you help me with this issue.

Please let me know if you want more information on the problems I want to solve.

Yours faithfully,

Can you give a short example of what an LMI is and what the solution would be?

Actually, this is what I want to do:

I checked the materials you supplied, but I'm afraid they won't help much. Any other ideas?

Thank you in advance!
