how to find tmin in YALMIP ?

[Chinna Obaiah]

Good afternoon John,

Thank you for your great work, it is very useful and easy to solve problem. I am new to YALMIP before that i am using LMI toolbox.

In my work, i want to check only feasible solution by getting tmin value.

Here my question is:

How to find tmin in YALMIP like in LMI toolbox.

In LMI toolbox, by using  "feasp" syntax we will find [tmin, xfeas]. 

In YALMIP, we are using "solvesdp" and "optimize" for solve LMI constraints. The output of these syntax only giving like

1. yalmiptime,

2. solvertime, 

3. info and 

4. problem.

How to get tmin for the feasibility problem in YALMIP like LMI toolbox 'feasp'.

It would be very useful for me.

Thank you.

tmin as the minimal objective value? You simply apply the value operator on the variable of interest
