coff             Scilab Group             Scilab Function              coff
NAME
   coff - resolvent (cofactor method)
  
CALLING SEQUENCE
 [N,d]=coff(M [,var]) 
PARAMETERS
 M    : square real matrix
      
 var  : character string
      
 N    : polynomial matrix (same size as M)
      
 d    : polynomial (characteristic polynomial poly(A,'s'))
      
DESCRIPTION
   coff computes R=(s*eye()-M)^-1 for M a real matrix.  R is given by N/d.
  
   N = numerator polynomial matrix.
  
   d = common denominator.
  
   var character string ('s' if omitted)
  
EXAMPLE
 M=[1,2;0,3];
 [N,d]=coff(M)
 N/d
 inv(%s*eye()-M)
