MATLAB thinks my entire script is commented, no idea why.
1 view (last 30 days)
After coming back from holiday MATLAB can't seem to be able to open my script. Every line appears to be commented out, even though there's no comment '%' indicators (single line or paragraph). Atatched is a screenshot of my problem. This only happens for this particular script, or any saved copies (such as saving script.m to scriptV2.m, etc...). Running the code does nothing.
I can't copy and paste any of the code except into a new script file within MATLAB, but it preserves this strange comment behaviour. So I can't copy it to a .txt file, then back. Nor can I copy it here to show you - when I try, it just copies a single % symbol.
I've tried saving my file as a .txt, then opening it, but when it saves it puts spaces between each letter, like "T H I S", meaning I can't use the code or paste it back into matlab.
I can write new, working code at the bottom, if I create enough new lines. But I can't edit, use or recover any of the existing code.
Can anyone help? I've also attached a deleted version of the code (as the main script contains sensitive infiormation/data) - if anyone can get it working or knows a fix, I'd be most grateful, or I'll have to re-type the entire document...

How was this file created? When I open the attached file in MATLAB, there are a lot more spaces between each letter.
When I open it in a text editor, I see those spaces are NUL characters.
If I remove the null characters, it is no longer treated as a comment. To do this, I highlighted the first character in line one, pressed Ctrl + H to open Find and Replaace, and made sure Replace was empty (delete anything there, including a space), and then clicked Replace All.
