how to remove vowels using matlab ?

pleas help me to answer this following question :

Remove all the vowels in the given phrase.

Example:

 Input  s1 = 'Jack and Jill went up the hill'

Output s2 is 'Jck nd Jll wnt p th hll'

[Walter Roberson]

Is "y" a vowel or not? If it is "sometimes" a vowel, should it be removed only if it is acting as a vowel?

Hi Walter, I looked at the Question, and then the answer. I thought it is done and the challenge is off. And cometh you., the man, with a new challenge.:)

[Walter Roberson]

Consider "yellow" and "yip" and "cry" and "ytterbium"

"y" is called a "semi-vowel". There are other semi-vowels used in English tat might have different rules. "w" is also considered a semi-vowel, but not (for example) in "vowel" or "cow"; notice the completely different "w" sound in "won" and "when".

"w" is also a semi-vowel, and acts like a vowel in situations such as "won" (followed by a short vowel), "wine" (followed by a long vowel), and "when" (followed by an "h" followed by a vowel.) But "w" does not act as a vowel in the word "vowel" nor in "how"

And Ä, ä, Ö, ö, Ü, ü :-)

[Walter Roberson]

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

[Andreas Goser]

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

Answer 1

[Jothi]

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

[Jan]

@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

jothi i think your answer is not working, can you please check again?

Answer 2

[Jan]

output = s1(~ismember(s1, 'aeiou'));

And considering uppercase vowels:

output = s1(~ismember(lower(s1), 'aeiou'));

Answer 3

[Andrei Bobrov]

regexprep(s1,{'a','e','i','o'},repmat({''},1,4))

or

regexprep(s1,'[aeio]','')

[Walter Roberson]

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