h_inf_st - static H_infinity problem

### Sequence d'appel

  `[Kopt,gamaopt]=h_inf_stat(D,r)`

### Parametres

- `D` : real matrix
- `r` : 1x2 vector
- `Kopt` : matrix

### Description

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 partionned as `D=[D11 D12; D21 D22]` where `size(D22)=r=[r1 r2]`
