I don't think those are semi-vowels, Andreas :)

Ah, I wasn't responding to Walter but was more generally mentioning such strange characters exist.

vow={'a','e','i','o','e'};
s1 = 'Jack and Jill went up the hill'
for i=1:5
output = strrep(s1, vow{i}, '');
s1=output;
end
output =
Jck nd Jll wnt up th hll

@Jothi: vow need not be a cell. strrep is efficient, but this is an alternative:
vow = 'aeioe';
s1 = 'Jack and Jill went up the hill'
for k = 1:5
s1(s1 == vow(k)) = [];
end

output = s1(~ismember(s1, 'aeiou'));
And considering uppercase vowels:
output = s1(~ismember(lower(s1), 'aeiou'));

regexprep(s1,{'a','e','i','o'},repmat({''},1,4))
or
regexprep(s1,'[aeio]','')

Too efficient for a beginner answer. As was the answer I almost posted but decided against a second ago.
