eps1p^2-A0’p-pA0-eps2A0’A0-eps3A1’A1-eps4A1A1’-eps5J’p^2J-eps6*eye(2,2)>=0;
eps=arbitrary positive for example 2 or 3 or0.5 …
p is unKnow 2×2 symmetric
A0 and A1 are matrix 2×2 know

Thanks, but
i can not write matlab code for this formula, because p and p^2 used to
same formula . i cannot convet this formuls to lmi. not problem in eps1_5
J is matrix 2×2 know with |J|<=1

However, I’m not clear what your problem is. Are eps1, eps2, eps3, eps4, eps5, and eps6 the only unknowns, i.e., optimization variables? If so, this just an LMI and can be entered in the straightforward manner:
