MATLAB: If statement for string

Question

Say I have something like

word='example'

and letter='e'

I'm trying write a if state for example

 if word contains letter
.......
 elseif word doesn't have letter
....
end

Answer 1

Use ismember:

if ismember(letter, word)
  %do something
else
  %do something else
end

Note the use of else and not elseif. There is no need to test for the false condition.
