diffalg.DiffOrd

compute the differential order of a differential polynomial

Syntax

$diffalg.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 Q[x[1..2,0..20]];
F:=x[1,4]^2-x[2,4]^3;
$diffalg.DiffOrd(F);
