pdiv - polynomial division
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 .
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
