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

Then why t(2,1) is repeated?

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

threshold=4;
x=11
c=1:threshold-1
P=s(1,1)+sum(text(c).*x.^c)

the value of text should be incremented for s(1,2)

If threshold=3 what should be the result?

Sharen, please fill in the blank and define the ranges:
P(m,n) = _________________________
(for m = 1:size(s,1) and n = 1:size(s,2)) <---- correct??
