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
