Is there a command or function to "autocorrect" words in a sentence? Such as correcting the sentence "Teh cow jumped over the mono." to "The" and "moon".

Such as correcting the sentence "Teh cow jumped over the mono." to "The" and "moon".

Answer 1

[Chad Greene]

You could create a list of commonly misspelled words and corresponding correct spellings. For example,

str = 'Teh cow jumped over the mono.'; 

common_misspellings = {'Teh','The';
                       'mono','moon';
                       'trowzers','pants'}; 

regexprep(str,common_misspellings(:,1),common_misspellings(:,2))   

ans =
The cow jumped over the moon.

But that is not auto-correct, which is what the question was about. Since the only place where such an operation would apply in MATLAB would be in the editor, you would need to worry about it catching variable names. Were you to apply that to an m-file, it would apply to everything, including variable names. Finally, the list of common misspellings could arguably be pretty long, so you would need to establish an entire dictionary.

@Chad Greene: mono is not a spelling mistake, it is a correctly spelled word in its own right. A solution that can parse sentences and distinguish between different word functions might be able to distinguish this, but as it stands it would be totally incorrect to use a simple list or even a dictionary to replace mono with moon. This concept would "correct" my sentence to read "My moon amplifier is broken", when in fact it was correct to begin with.

The best and easy solution will be to add a spell checker only on commented lines.

Not in the MATLAB Editor.

This was actually discussed a while back in some thread. Since it’s possible that someone would want to name a variable ‘Teh’, or ‘summ’ to avoid overshadowing the sum function, the consensus was to just leave well enough alone.

[John D'Errico]

Many people would be unhappy if the editor started to do this, because it would suddenly start creating bugs in their code.

[Chad Greene]

I don't think the question is about misspelled variable names.

Let MS Word do this for you:

and in Unix? Why not just spell check the commented lines only? everything after % sign etc...
