## 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); 7 -------------------------------
