LMI matlab toolbo

[Hamid]

Hello Johan.

I would to use LMIlab and minCx function in my work.

I want to minimize : 

trace (P * L0)

where P is a variable matrix (for example P  = lmivar(1,[2 1])) and L0 is a known matrix (for example L0 =[1 3; 4 5]).

But i don't know who i can define in trace in lmilab.

Do you can help me?

No.

This is a group for YALMIP.

...and the fact that it is unclear how to express trace(P*L0) in lmilab is a perfect illustration that lmilab severly lacks as a modeling language. The YALMIP code would be

trace(P*L0)
