Simplifying the built-in function [q,r]=deconv(b,a)

Create an efficient function [q,r]=deconc_e(b,a) to eliminate the undesired data that resulted from running the existing built-in function

In the polynomial division, such as b(x)/a(x)=q(x)+r(x)/b(x) or
where we denote length of b,a,q,r as Lb,La,Lq,Lr, respectively.

Then using the built-in function,
We get our desired answers: q,r,

However, it is Lr=Lb instead of Lr=La-1 for La<Lb.
The unwanted data ahead the desired r should be completely eliminated, even they are very very small..

The presented function
will resolve this problem,
