You have functions to smooth the data.....read about smooth.

Answer 1

[KSSV]

Let P be your 10000x1 array.

p0 = p ; 
% To change data from 4901 to 4949
for i = 4901:4949
    p(i) = (p(i)+p(i+1))/2 ; 
end

You can also do the same without loop.

i = 4901 : 4949 ;
p(i) = (p(i)+p(i+1))/2 ;

You can use movmean(), smooth(), or conv().
