Section headers are formatting as comments: how to get SH working again?

My section headers are formatting as comments. I was editing my code and was commenting out a block. I entered "%}" in first, and it didn't comment out when I wrote the %{ above it. Since then, my section headers are not functioning. The SH have default color settings and I can't run individual sections either. Does someone know what I messed up?

Answer 1

You have an error in your code near the end of the file. You're missing the loop variable.

for 1:totalNumberOfFiles

Because of that error, your code is not a valid MATLAB script. Fix that error and the Editor will be able to enable section mode.

To detect this, I copied your code into MATLAB Editor and looked along the right margin of the Editor for the red line indicating Code Analyzer has detected an error.

Thank you! I didn't know that could cause that error!

From the home tab, under the ENVIRONMENT panel, select preferences. Expand the "Editor/Debugger" option from the list, then go to "autoformatting".

Under the "Section Break" section, are both of the boxes checked (they should be)?

[Samuel Veith]

Yeah, everything is checked on that page. I can type section headers on different codes, but not this one. If I copy the code into another file, I can also no longer write section headers in that file.

[AdamG2013468]

You may have to copy your actual code into this question for further troubleshooting. Use the code feature (alt+enter) to use MATLAB formatting.

Bummer. I hope that this code doesn't reveal how bad a programmer I am!
