how to represent binary values as polynomial expression?

hello ,

   i m working with cyclic codes,where i have to generate polynomial expression for the binary sequences for example
 a=[1 0 1 1]
i tried with poly2sym(a)..it worked..
my problem is when a=1011 i m getting output as 1..
similary i have to generate polynomial xepression for 16 possible bits.
plz,suggest me...

My suggestion:

a=1011
tmp = sprintf('%i',a);
a = str2num(sprintf('%c ',tmp(:)));
poly2sym(a)

[Walter Roberson]

a=1101;

poly2sym(sprintf('%d',a) - '0')
