pdiv
====

polynomial division



Calling Sequence
~~~~~~~~~~~~~~~~


::

    [R,Q]=pdiv(P1,P2)
    [Q]=pdiv(P1,P2)




Arguments
~~~~~~~~~

:P1 polynomial matrix
: :P2 polynomial or polynomial matrix
: :R,Q two polynomial matrices
:



Description
~~~~~~~~~~~

Element-wise euclidan division of the polynomial matrix `P1` by the
polynomial `P2` or by the polynomial matrix `P2`. `Rij` is the matrix
of remainders, `Qij` is the matrix of quotients and `P1ij = Qij*P2 +
Rij` or `P1ij = Qij*P2ij + Rij`.



Examples
~~~~~~~~


::

    x=`poly`_(0,'x');
    p1=(1+x^2)*(1-x);p2=1-x;
    [r,q]=pdiv(p1,p2)
    p2*q-p1
    p2=1+x;
    [r,q]=pdiv(p1,p2)
    p2*q+r-p1
