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

s=[2 3 ;4 5]

text = [3 5 6 7 3 4 5 6]

threshold=4;

x=11

c=1:threshold-1

P=s(1,1)+sum(text(c).*x.^c)

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??
