DA.Weight
Computes the weight of a differential polynomial.
Syntax
DA.Weight(F:POLY):INT
Description
Computes the weight of the differential polynomial F.
@param F A differential polynomial.
@return The weight of F.
Example
Use QQ[x[1..2,0..20]]; F:=x[1,2]^2x[1,1]3+x[2,1]; DA.Weight(F); 5 ------------------------------- F:=x[1,2]^2x[1,1]^3+x[2,1]; DA.Weight(F); 7 -------------------------------
