f02ajf

f02ajf © Numerical Algorithms Group, 2002.

Purpose

F02AJF All eigenvalues of complex matrix (Black Box)

Synopsis

[rr,ri,ifail] = f02ajf(ar,ai<,ifail>)

Description

 
 The complex matrix A is first balanced and then reduced to upper 
 Hessenberg form using stabilised elementary similarity 
 transformations. The eigenvalues are then found using the 
 modified LR algorithm for complex Hessenberg matrices.

Parameters

f02ajf

Required Input Arguments:

ar (:,:)                              real
ai (:,:)                              real

Optional Input Arguments:                       <Default>

ifail                                 integer  -1

Output Arguments:

rr (:)                                real
ri (:)                                real
ifail                                 integer
