if the word is "matlab_ans.wer" it should display "matlab ans" if the word is "matlab_ask_a_question" it should display
"matlab ask a quest"
that is delete "wer" and "ion" and insert a space in place of underscore and just delete the full stop if any...

In such cases, edit instead of starting a new question.

Strings are pretty much like vectors, simply get rid of the last 3 entries:
s = s(1:end-3);
As for the rest, have a look at strrep and/or regexprep.
