D.2.8.9 maxdeg1
Procedure from library poly.lib (see poly_lib).
- Usage:
- maxdeg1(id[,v]); id=poly/ideal/vector/module/matrix, v=intvec
- Return:
- integer, maximal [weighted] degree of monomials of id independent of
ring ordering, maxdeg1 of i-th variable is v[i] (default: v=1..1).
- Note:
- This proc returns one integer while maxdeg returns, in general,
a matrix of integers. For one polynomial and if no intvec v is given
maxdeg is faster
Example:
| | LIB "poly.lib";
ring r = 0,(x,y,z),wp(1,2,3);
poly f = x+y2+z3;
deg(f); //deg returns weighted degree (in case of 1 block)!
==> 9
maxdeg1(f);
==> 3
intvec v = ringweights(r);
maxdeg1(f,v); //weighted maximal degree
==> 9
matrix m[2][2]=f+x10,1,0,f^2;
maxdeg1(m,v); //absolute weighted maximal degree
==> 18
