Deg
Syntax
Deg(F:POLY or VECTOR):INT
Deg(F:POLY or VECTOR,X:INDET):INT
Summary
the degree of a polynomial or vector
Description
The first form of this function returns the (weighted) degree of F.
The second form returns the (un-weighted) degree of the indeterminate
X in F. In either case, if F is a vector, the maximum of the degrees
of its components is returned. (For the degree of a ring or quotient
object, see
Multiplicity
.)

Use R ::= Q[x,y];
