MATLAB: Is there any way to check spelling from within MATLAB

checkcheckingMATLABspellspellcheckword

I would like to be able to check the spelling of a word within MATLAB without having to write my own spell checking algorithm.

There is currently no spell checking functionality contained in MATLAB. However, using ActiveX, you can implement the spell checker of another program and bring the results back to MATLAB. The following example shows how to do this using Microsoft Word's spell checker:

function suggestion = checkSpelling(word)
%CHECKSPELLING  uses MSWord to correct spelling
%   CHECKSPELLING(WORD) checks the spelling of WORD and returns spelling
%   suggestions as a cell array.  If WORD is spelled correctly, CHECKSPELLING 
%   will return empty brackets.  If no suggestions are found.  CHECKSPELLING
%   returns 'no suggestions'.  
%Start the Word ActiveX Server and check the spelling of WORD
h = actxserver('word.application');
h.Document.Add;
correct = h.CheckSpelling(word);
if correct
      suggestion = []; %return empty if spelled correctly
else
      %If incorrect and there are suggestions, return them in a cell array
      if h.GetSpellingSuggestions(word).count > 0
          count = h.GetSpellingSuggestions(word).count;
          for i = 1:count
              suggestion{i} = h.GetSpellingSuggestions(word).Item(i).get('name');
          end
      else
          %If incorrect but there are no suggestions, return this:
          suggestion = 'no suggestions';
      end
end
%Quit Word to release the server
h.Quit

Currently there is no workaround for platforms other than Windows.

UPDATE : here is a slightly modified version (also attached)

 function wordsChecked = checkWordsSpelling( words )
    %

    %   Based on Mathworks thread:
    %   http://www.mathworks.com/matlabcentral/answers/91885-is-there-any-way-to-check-spelling-from-within-matlab
    %
    % - Split space-separated words into cell array of words, or wrap
    %  single word into cell array.
    if ischar( words )
        if any( words == ' ' )
            words = strsplit( words, ' ' ) ;
        else
            words = {words} ;
        end
    end
    % - Launch MS Word and create document.
    h = actxserver( 'word.application' ) ;
    h.Document.Add ;
    % - Build cell array of originals and suggestions.
    words  = words(:) ;      % -> columns cell array.
    nWords = numel( words ) ;
    for wId = 1 : nWords
        % - Check if spelling correct. Loop back if so.
        isCorrect    = h.CheckSpelling( words{wId,1} ) ;
        words{wId,2} = isCorrect ;
        if isCorrect
            words{wId,3} = false ;
            continue ;
        end
        % - Build cell array of suggestions.
        nSug = h.GetSpellingSuggestions( words{wId,1} ).count;
        words{wId,3} = nSug > 0 ;
        if nSug > 0
            for sId = 1 : nSug
                words{wId,4}{sId} = ...
                    h.GetSpellingSuggestions( words{wId,1} ).Item(sId).get( 'name' ) ;
            end
        end
    end
    % - Quit MS Word.
    h.Quit
    % - Build table (or struct array if you prefer).
    %wordsChecked = cell2struct( words, {'original', 'isCorrect', 'hasSuggestion', 'suggestion'}, 2 ) ;
    wordsChecked = cell2table( words, 'VariableNames', {'original', 'isCorrect', 'hasSuggestion', 'suggestion'} ) ;        
 end

With that, you can do the following:

 >> checked = checkWordsSpelling( 'Helloo' )
 checked = 
    original    isCorrect    hasSuggestion              suggestion           
    ________    _________    _____________    _______________________________
    'Helloo'    false        true             'Hello'    'Halloo'    'Hellos'
 >> checked = checkWordsSpelling( 'Helloo Wolrd Hello' )
 checked = 
    original    isCorrect    hasSuggestion    suggestion
    ________    _________    _____________    __________
    'Helloo'    false        true             {1x3 cell}
    'Wolrd'     false        true             {1x2 cell}
    'Hello'     true         false            []        
 >> checked.suggestion{2}
 ans = 
    'World'    'Word'
 >> checked = checkWordsSpelling( {'Helloo', 'Wolrd'} )
 checked = 
    original    isCorrect    hasSuggestion    suggestion
    ________    _________    _____________    __________
    'Helloo'    false        true             {1x3 cell}
    'Wolrd'     false        true             {1x2 cell}

Hope it helps!

MATLAB: Are the ActiveX handles to Microsoft Word not automatically freed when they lose scope in MATLAB 6.5 (R13)

To properly remove the ActiveX object to the Word application involves the use of the QUIT function and then the DELETE function. Note that this is a feature of Microsoft Word and not related to our ActiveX controls.

Here is a simple example to properly free the ActiveX handle to Word:

h = actxserver('Word.Application');
invoke(h, 'quit');
delete(h);

If the above code is executed within a function MATLAB function, the DELETE function is not required.
