normalize


Usage

normalize L
normalize p


Parameter Type Description
L ${\mathbb{Q}}[n,E]$ A difference operator
p ${\mathbb{Q}}[n]$ A polynomial


Description

normalize makes its argument monic in the outermost variable.


Remarks

normalize can also be used on vectors and quotients of polynomials.


Example

1 --> L := n*E^2 - E + n^2 + n;
2 --> tex(normalize(L));

\begin{displaymath}
E^{2}-{{1} \over {n}}\,E+n+1
\end{displaymath}

3 --> f := (2*n + 1)/(3*n^2 - 1);
4 --> tex(normalize(f));

\begin{displaymath}
{{n+{{1} \over {2}}} \over {n^{2}-{{1} \over {3}}}}
\end{displaymath}
