Scilab Function

fstair - computes pencil column echelon form by qz transformations

Calling Sequence

[AE,EE,QE,ZE,blcks,muk,nuk,muk0,nuk0,mnei]=fstair(A,E,Q,Z,stair,rk,tol)

Parameters

Description

Given a pencil sE-A where matrix E is in column echelon form the function fstair computes according to the wishes of the user a unitary transformed pencil QE(sEE-AE)ZE which is more or less similar to the generalized Schur form of the pencil sE-A. The function yields also part of the Kronecker structure of the given pencil.

Q,Z are the unitary matrices used to compute the pencil where E is in column echelon form (see ereduc)
