hrmt(1)                        Scilab Function                        hrmt(1)
NAME
  hrmt - gcd of polynomials

CALLING SEQUENCE
  [pg,U]=hrmt(v)

PARAMETERS

  v    : row of polynomials i.e. 1xk polynomial matrix

  pg   : polynomial

  U    : unimodular matrix polynomial

DESCRIPTION
  [pg,U]=hrmt(v) returns a unimodular matrix U and  pg = gcd of row of poly-
  nomials v such that v*U = [pg,0].

EXAMPLE
  x=poly(0,'x');
  v=[x*(x+1),x^2*(x+1),(x-2)*(x+1),(3*x^2+2)*(x+1)];
  [pg,U]=hrmt(v);U=clean(U)
  det(U)

SEE ALSO
