Are you sure you don't want to do something like
str = 'I live in a city called hilla this city located in.the center of iraq it is not too large hilla contain many resturants in here road.these resturants make very good and delicious food.one of city that near by called najaf'
dotLocations = find(str == '.')
% Assume tos are periods - end of sentence.
% Make sure the next character is Capitalized
str(dotLocations+1) = upper(str(dotLocations+1))
% Now replace dot with dot space since sentences
% don't start immediately after a period.
str = strrep(str, '.', '. ')
% Make sure the string ends with a period.
if ~strcmp(strtrim(str(end)), '.')
% Get rid of leading and trailing spaces and end with a period.
str = [strtrim(str), '.']
end
Now there are some places where you have a period at places that don't make grammatical sense, like 'in.the' but unless you want to put in a grammar analyzer, it's not possible to know whether to remove that period or replace it with a space.
Same problem for where period are totall missing, like 'of iraq it is not'. Only a full grammatical analysis would know that it's supposed to be 'of iraq. It is not' and to add the period and capitalize the next sentence.

Use strrep, which is designed to perform the task that you want:
>> str = '.Hello.World.';
>> strrep(str,'.','')
ans = HelloWorld

@hiba rashed: try something like this:
I = strrep(I{1},'.',' ')
I(end) = '.'
