Abstract
The cofactors of ![[sI-A]](/images/tex/4087.gif)
are the key to accurate, efficient calculation of ![[sI- A]^{-1}](/images/tex/4088.gif)
and 
, where aij is an element of 
. These cofactors can be evaluated by transforming their equivalents to phase variable or quasi-phase variable form. The procedure for forming the equivalent cofactors is the principal topic of this note.
