CoCoA:LM

LM

the leading monomial of a polynomial or vector

Description

This function returns the leading monomial of P. The monomial

includes the coefficient. To get the leading term of P, (which does

not included the coefficient), use <ttref>LT</ttref>.

Example

  Use R ::= Q[x,y];
  LM(3x^2y + y);
3x^2y
-------------------------------
  LM(Vector(2x,y));
Vector(2x, 0)
-------------------------------
  LT(Vector(2x,y));
Vector(x, 0)
-------------------------------
