MATLAB: How to generate a polynomial

MATLABpolynomial

i have two matrix one is
s=[2 3
   4 5]
other is
 text = [3 5 6 7 
         3 4 5 6]
based on my threshold value i should form a polynomial
say for exam threshold is 2 my polynomial should be
P= s(1,1)*x^0 + text(1,1)*x^1
if threshold is 3 my polynomial should be
P= s(1,1)*x^0 + text(1,1)*x^1 + text(1,2)*x^2 i have to process for every
digit like this …. value from should be taken once but from text van be any
number of times based on threshold…
Thanks in advance ..i am not able to trace it out please help

s=[2 3 ;4 5] 
text = [2 3 4; 5 6 7; 4 5 6]
t=text.'
t=t(:)
th=3;
x=11
[n,m]=size(s)
c=1:th-1;
idx1=1;
idx2=th-1;
for k=1:n
  for l=1:m
      t1=t(idx1:idx2).'   
      P(k,l)=s(k,l)+sum(t1.*x.^c)
      idx1=idx1+th-1
      idx2=idx2+th-1
  end
end
