mucomp

mu (structured singular value) calculation

Calling Sequence

[BOUND, D, G] = mucomp(Z, K, T)

Arguments

:Z the complex n-by-n matrix for which the structured singular value

is to be computed

: :K the vector of length m containing the block structure of the

uncertainty.

: :T the vector of length m indicating the type of each block. T(I) =

1 if the corresponding block is real T(I) = 2 if the corresponding block is complex.

: :BOUND the upper bound on the structured singular value. : :D, G vectors of length n containing the diagonal entries of the

diagonal matrices D and G, respectively, such that the matrix Z’*D^2*Z + sqrt(-1)*(G*Z-Z’*G) - bound^2*D^2 is negative semidefinite.
