Try this:

indxC = [1,7];
s ='hello world';
s(indxC) = upper(s(indxC))

or more generally:

s ='hello world';
upperS = upper(s); % Create an ALL CAPITALS VERSION of s.
spaceLocations = find(s(1:end-1) == ' '); % Find spaces - we'll capitalize the location after a space.
spaceLocations = [0, spaceLocations] % Always capitalize the first letter, so prepend 0.
s(spaceLocations + 1) = upperS(spaceLocations + 1) % Replace these locations with upper case letters.

When i use the first one, s(indxC) is printed like HW, So just the indexes are printed not ‘Hello World’

After copying and pasting, this is what I get:

s =

'Hello World'

So I don't know what you mean when you say that just the indexes are printed, and not 'Hello World'. Please post a screenshot.
