MATLAB: Subfunction in script

Question

can one not use subfunction in script? Here is my attempt:

phrasemat=char('Hello','how are you', 'How is it going?', 'what is up?')

[r c]=size(phrasemat)

for i=1:r

    howmany=countblanks(phrasemat(1,:));
    fprintf('Phrase %d had %d blanks\n',i,howmany)
end
    function num=countblanks(phrase)
    num=length(strfind(strtrim(phrase),'');
    end

Answer 1

No, subfunctions in scripts are not allowed.

This has been discussed repeatedly. See:

• want-to-have-m-function-in-m-script
• do-not-want-to-have-m-function-in-m-script
• don-t-care-to-have-m-function-in-m-script

[EDITED] Since R2016b you can define subfunctions in scripts also: https://www.mathworks.com/help/matlab/matlab_prog/local-functions-in-scripts.html
