DA.LPot
Computes the leading power of a differential polynomial.
Syntax
DA.LPot(F:POLY):POLY
Description
DA.LPot returns the leading power of polynomial F wrt. the current differential term order, or the hereby induced ranking respectively.
@param F A differential polynomial.
@return The leading power of F.
Example
Use QQ[x[1..2,0..20]];
Use QQ[x[1..2,0..20]], Ord(DA.DiffTO("Lex"));
DA.LPot(x[1,1]^2x[1,2]^2 + 1/4x[1,2]);
-------------------------------
