static H_infinity problem
[Kopt, gamaopt] = h_inf_stat(D, r)
real matrix
1x2 vector
matrix
computes a matrix Kopt
such that largest singular value of:
lft(D,r,K)=D11+D12* K*inv(I-D22*K)* D21
is minimal (Static H_infinity
four blocks problem).
D is partitioned as D=[D11 D12; D21 D22]
where size(D22)=r=[r1 r2]
