DA.DiffOrd

Computes the differential order of a differential polynomial.

Syntax

DA.DiffOrd(F:POLY):INT

Description

Computes the differential order of the differential polynomial F. The differential order is the maximum order of the derivatives occuring in the terms of F.

  • @param F A differential polynomial.

  • @return Order of F.

Example

Use QQ[x[1..2,0..20]];
F:=x[1,4]^2-x[2,4]^3;
DA.DiffOrd(F);
