- % ----------------------------------------------------------------
- % LINF solves the infinity-norm control problem via the Youla
- % parameterization and optimal Hankel approximation.
- %
- % Input data: augmented plant
- % (A,B1,B2,C1,C2,D11,D12,D21,D22) (Note: in upper case !!)
- %
- % Output data: controller F(s) := (acp,bcp,ccp,dcp)
- % CLTF Ty1u1 := (acl,bcl,ccl,dcl)
