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); ------------------------------- 4 -------------------------------
