how to display a word in a format

i have a word... i want to delete the last three alphabets of the word... what shud i do... also if the word has any underscore or full stop it should also be deleted.... please do reply...

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...

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.
