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 Q[x[1..2,0..20]];
F:=x[1,2]^2x[1,1]3+x[2,1];
DA.Weight(F);
-------------------------------
F:=x[1,2]^2x[1,1]^3+x[2,1];
DA.Weight(F);
