## Name

mucomp — mu (structured singular value) calculation

## Calling Sequence

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

## Parameters

- 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.

## Description

To compute an upper bound on the structured singular value for a given square complex matrix and given block structure of the uncertainty.
