How many of the hundreds of thousands of different Optical Character Recognition methods did you try?
The entire field is known as Optical Character Recognition (OCR), so any method that you used would be ocr. If you say that ocr is not accurate enough, you are saying that you have already tried the best possible method of recognizing the characters under the situation and found it lacking. Anything else you try would be another ocr method and thus, according to you, not accurate.

I also have some problems about reading numbers in MATLAB.
The following is my script in MATLAB.
EEG = pop_runica(EEG, 'icatype', 'runica', 'extended',1,'interrupt','on','pca',setname_in7); Thia line I need to read different number according to subject parameter
sub_ch1 = [8, 8, 9, 5, 10, 7, 6, 19, 7, 2, 18, 11, 11, 9, 15, 19, 6, 16];
sub_ch2 = 127 - sub_ch1;
But I do not know how to invoke each of them when read each subject data.
Looking forward to your reply. Thank you very much.
set_numbers = [1, 3, 4, 5, 6, 7, 8, 10, 12, 13, 15, 16, 17, 18, 20, 22, 23, 26];
sub_ch1 = [8, 8, 9, 5, 10, 7, 6, 19, 7, 2, 18, 11, 11, 9, 15, 19, 6, 16];
sub_ch2 = 127 - sub_ch1;
for K = set_numbers; N = sub_ch2;
setname_in6 = sprintf('M%02d_AD1dfcr.set', K);
setname_out6 = sprintf('M%02d_AD1dfcri', K);
setname_in7 = sprintf(sub_ch2, N);
EEG.etc.eeglabvers = '2020.0'; % this tracks which version of EEGLAB is being used, you may ignore it
EEG = pop_loadset('filename', setname_in6,'filepath','C:\\EEG_OVGU\\AD1\\');
EEG = eeg_checkset( EEG );
EEG = pop_runica(EEG, 'icatype', 'runica', 'extended',1,'interrupt','on','pca',setname_in7);
EEG = eeg_checkset( EEG );
EEG = pop_saveset( EEG, setname_out6 );
EEG = eeg_checkset( EEG );
end

This does not seem to have anything to do with Optical Character Recognition. You should create a new Question for it. In that new question, you should expand on your question about what it means to you to "invoke each of them".
