Spell check with txt file

Asked by Kim
on 23 Feb 2013
For each word in the email, check whether the word is in the dictionary. 
Print out misspelled words.

How can you check whether the word in "sentence.txt" is in "text.txt"?

Also how can you print words not in text.txt file?



For example:

There is no one in th hous.

(It should check this sentence to "text.txt" and print out th & hous because it is not in "sentence.txt" file.)

 CStr = textread('sentence.txt', '%s', 'delimiter', '\n')
 CStr1 = textread('text.txt', '%s', 'delimiter', '\n')
 contained = ismember(CStr, CStr1)  % if ans 1 then it is in text.txt
 notIndata2 = CStr(~contained)     % print those are not in text.txt 
 notIndata2 = CStr(contained)      % print those are in text.txt

Yes. In an application such as you describe, I can see a use for all of those except str2num (but not all of what you list might be needed in any one implementation.)

If your question is not a homework project, which I hope it is not, then 'textread' is part of base-MATLAB and you should use it. Why go for the elementary functions?

it is a homework project, and it recommends to use those functions but I don't know how to :(
