>> regexprep('How to read only vowels of a string?', '[^aeiouAEIOU]', '')
ans =
'ooeaooeoai'
>> char(regexp('How to read only vowels of a string', '[aeiouAEIOU]', 'match'))'
ans =
'ooeaooeoai'
(edit) No longer ignoring capitals!

Certainly, if you have the trimmed down character vector:
vowels = regexprep('How to read only vowels of a string?', '[^aeiouAEIOU]', '')
%{
vowels =
'ooeaooeoai'
%}
you could use histc:
bins = sort('aeiouAEIOU');
counts = histc(double(vowels), double(bins));
for v = bins
fprintf('%c: %d\n', v, counts(bins==v));
end
%{
A: 0
E: 0
I: 0
O: 0
U: 0
a: 2
e: 2
i: 1
o: 5
u: 0
%}
