Undefined function or variable 'filename'
41 views (last 30 days)
Whenever I try to execute my .m file, I get the error message popping up: "Undefined function or variable 'filename' ".
I've recently reorganised my files and moved this particular file to a new location. I have added the file to the path again and I'm in the correct directory.
Does anyone know what could be causing this now?

The error means you are using filename as a variable or function but have not created it or defined it yet. Given the choice of name, I suspect you intended it to be a variable. Look at your code (the error message will tell you exactly what line) and see if you ever assign a value to filename.
If that's not it, we can't do much more than guess unless you are willing to share your code. Also, it's best to share the full error message (copy/paste all the red text) here.
