I'm wondering if it is possible to check if a string contains a certain letter.
I have an array with different strings and I would like to find every cell that contains a certain letter.
'hi'
'my'
'name'
'is'
How would I find the cells containing the letter i?

Many ways to do this:
c = {'hi'; 'my'; 'name'; 'is'}
lettertofind = 'i';
%method 1: plain character comparison
cellfun(@(s) any(s == lettertofind), c)
%method 2: strfind
cellfun(@(s) ~isempty(strfind(s, lettertofind)), c)
%method 3: ismember
cellfun(@(s) ismember(lettertofind, s), c)
%etc.

% regexp
~cellfun(@isempty,regexp(c,'i'))
% strcmp
~strcmp(strrep(c,'i','x'),c)
