# 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 + Qij` or `P1ij = Qij*P2ij + Qij`.

### 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```
