Mekala - you will need to write code that recognizes the words in your sentences and then reverse the order of the words. Using fliplr or reverse will just flip or reverse the characters in your strings/array. Perhaps strtok might be useful.

There's undoubetly better solutions, but:
strtrim(strrep(cell2mat([flipud(split('Hello. I. am. Here.'))']),'.','. '))

Sounds like homework, so here is a hint towards the solution:
str = 'Hello. I. am. Here.'
words = strsplit(str)
reverseWords = words(end:-1:1)
