I have a function:
function [ vowels ] = findVowels( charCell )
%FINDVOWELS
% charCell: a two-dimensional cell array and each cell contains a
% character array
% vowels: a cell array with the same dimensions as charCell that contains
% only the vowels of each entry, in lower case
vowels=charCell;
switch vowels
case strfind(charCell, 'a')
disp('a')
case strfind(charCell, 'e')
disp('e')
case strfind(charCell, 'i')
disp('i')
case strfind(charCell, 'o')
disp('o')
case strfind(charCell, 'u')
disp('u')
end
end
And I want the function to search for the vowels and RETURN those vowels for example:
>>X={'hi','hello';'goodbye', 'later'};
>>findVowels(X)
ans=
2x2 cell array
'i' 'eo'
'ooe' 'ae'
My current function results in an error because vowels is not a scalar or a character. How do I go about this to produce a character?

Your variable vowels is a cell array. You cant switch based on a cell array. Instead take each word, and run a for loop on each character. some thing like this,
for iLoop=1:length(charCell)
sCurrentWord = charCell{iLoop};
if ~isempty(strfind(charCell, 'a'))
disp('a')
end
if ~isempty(strfind(charCell, 'e'))
disp('e')
end
..and so on..
end
I would suggest to use regexp instead.
