parrot - Parrot's problem

Calling Sequence

K=parrot(D,r)

Parameters

• D,K : matrices
• r : 1X2 vector (dimension of the 2,2 part of D)

Description

Given a matrix D partionned as [D11 D12; D21 D22] where size(D22)=r=[r1,r2] compute a matrix K such that largest singular value of [D11 D12; D21 D22+K] is minimal (Parrot's problem)
