Thank you all, I have a string of about 80 words and i want to check if at least one word from the string is contained in the text that is extracted from a website.

matchpattern = ['(?<=\W)', strjoin(WordListCell, '(?=\W)|(?<=\W)'), '(?=\W)' ];
results = regexp(txt, matchpattern, 'match');
This would be for the case of exact matches of words -- so for example plurals would not be matched, and words with article prefix characters would not be matched. I do not promise that \W knows about the proper classification of Hebrew characters.

Read about strfind, strcmp, strcmpi and regexp.

What about simply using the contains() function?
Description
TF = contains(str,pattern) returns 1 (true) if str contains the specified pattern, and returns 0 (false) otherwise.
If pattern is an array containing multiple patterns, then contains returns 1 if it finds any element of pattern in str.

Note: contains() does not check word boundaries. For example it would find "his" in "this".
