How do I solve this cvx problem? Please Help I'm getting an error

the code I’m trying to execute is:
pi_ss = 0.1; pi_su = 0.9; pi_us = 0.5; pi_uu = 0.5;
cvx_begin quiet
variable Y(2)
(A/Ps + BY’)’ * (pi_ssPs+pi_suPu) * (A/Ps+BY’) - inv(Ps)<= - eps*eye(2);

where A is a 2x2 and B is a 2x1 matrix. Ps and Pu are positive definite matrices of order 2x2.

I’m getting the ERROR:
Error using * (line 126)
Disciplined convex programming error:
Only scalar quadratic forms can be specified in CVX.

I do not understand why I’m getting this error.

See my answer at How do I write this LMI constraint in cvx format? (Moderator note: LMIs are convex, but this is not an LMI.)
