deconv function remainder won't appear

hi I'm trying yo divide two arrays using the decent, i know it uses polynomial division and how it works but i wrote this function as a test to see whether it worked and i only get one answer and that the quotient... why is there no remainder when there should be? have i written it wrong?

 function [q,r] = arraydiv(c,u)
 [q,r] = deconv(c,u);
 end

i have c=[1,5] and u=[1,2] (just a simple example) so when i try to use the function all i get is ans =1 but there should be a remainder? and shouldn't it say q=1 r=3?

thankyou I'm sure I'm just doing something stupid

Zoe, you need to call the function the same way it is defined. In other words, use

 c = [1,5]; 
 u = [1,2];
 [q,r] = arraydiv(c,u)
 q =
     1
 r =
     0     3

I assume you used

 arraydiv(c,u)
 ans =
     1

Knew i was doing something stupid. i was typing in arraydiv(c,u) Thankyou :)
