I have two Lmis to solve,and I use lmi toolbox.

The question is:
the first lmi I use a matrix variable X(s.t lmi(1,[4,1])).
but in the second lmi,I have to use the inverse of the variable X.
How can I represent the inverse of variable X in the second without define a new variable?

Thanks for help
