MATLAB: Can someone help me with this

loopseparate the wordstringstring vectorvector

I want to separate the word for the string vector by using loop. For example I have a str= 'hello,my,word' Then I want my result to be by using loop, so I can using index to call such as below: word(1)=hello word(2) = my word(3) = word I want to make it work in general case too. Can someone help me with this? Thank you

First, read this:

help strfun

Look at the functions you will find there. Read the help for those that might seem to be of use.

str= 'hello,my,word'
str =
    'hello,my,word'
strsplit(str,',')
ans =
  1×3 cell array
    {'hello'}    {'my'}    {'word'}

Use regexp, and adapt the regular expression to suit whatever your definition of word is. The words are all returned in the output cell array C:

>> str = 'Hello world! All is Well';
>> C = regexp(str,'\w+','match');
>> C{:}
ans = Hello
ans = world
ans = All
ans = is
ans = Well
>>

Note that there is no universal definition of what a "word" is, and beginners invariably forget about hyphens (e.g. "mother-in-law"), apostrophes (e.g. "can't"), etc.). The more specific your definition of "word" is, the more precisely you can define the regular expression to suit.

MATLAB: How to Count every word with three or more syllables in each group of sentences, even if the same word appears more than once.

The only way you can do this is by using a database of word-syllable. Here's one way using www.dictionary.com as the database.

FullText = 'This is a really arbitrary sentence.'; 
%'really' could be pronounced 'ree-uh-lee' (3 syl)
TextCell = regexp(FullText, '\w+', 'match'); 
TextSyl = cellfun(@(x) getSyllable(x), TextCell);
TextSyl =
     1     1     1     3     4     2  
OneSylWord = sum(TextSyl == 1);
OneSylWord = 
     3

Where getSyllable function is:

function Syl = getSyllable(Word)
if nargin == 0
    Word = input('What word do you want? ', 's');
end
if isempty(Word)
    Syl = 0;
    return
end
Word = strrep(Word, ' ', '');
% Use dictionary.com to get the phonetic transcription of a word
%  Ex: arbitrary
%    [ahr-bi-trer-ee]
% WARNING: will not work for some words if dictionary.com does not have it
%  listed as the main word. Example, 'awesomeness' returns 2 because
%' awesome' is the main word in the site.
try
    SiteTxt = urlread(sprintf('http://www.dictionary.com/browse/%s?s=t', Word));
catch
    warning('Could not determine syllable for "%s". Returning 0.', Word);
    Syl = 0;
    return
end
CodeSrch1 = '"pron spellpron"[\s\w\d\>]+\[\s*(?<InnerCode>[^\]]+)';
InnerCode = regexp(SiteTxt, CodeSrch1, 'tokens');
InnerCode = InnerCode{1};
CodeSrch2 = '>(?<Phonetics>[^\<]+)';
Phonetics = regexp(InnerCode, CodeSrch2, 'tokens');
Phonetics = [Phonetics{1}{:}];
if isempty(Phonetics)
    Syl = 1;
else
    Phonetics = cat(2, Phonetics{:});
    MultWord = regexp(Phonetics, ',', 'split'); %Sometimes many ways to say a word - take 1st option
    Syl = sum(MultWord{1} == '-') + 1;
end
