|L||A differential operator of order at most 3|
Returns one of the following possible results:
We factor the differential equation
1 --> L := D^3-x*D^2+(-x^2+1)*D-3*x+x^3; 2 --> v := factor(L); 3 --> tex(v);
This means that the operator of (5) is a least common left multiple of and of the product , which itself is not a least common left multiple of irreducible operators.
Usage within MAPLE
> L := D^3-x*D^2+(-x^2+1)*D-3*x+x^3; > dfactor(L, D, x);
