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.

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