CoCoA:LPP

LPP

the leading power-product of a polynomial or vector

Description

This function returns the leading power-product of P.

Example

  Use R ::= Q[x,y];
  LPP(3x^2y+y);  -- LPP is the same as LT for polynomials
x^2y
-------------------------------
  LPP(Vector(2x,y));
x
-------------------------------
  LT(Vector(2x,y));  -- Note the difference between LPP and LT
                     -- for vectors.
Vector(x, 0)
-------------------------------
