Checking Which Files Are Open in Octave

When working with files in Octave, it's important to remember to open a file before performing any read and/or write operations, and to close the file when you're done.

However, if you're not sure which files are currently open, you can use the freport() command

>>> freport()

This command will display a list of all the files that are currently open in Octave.

By checking the list of open files using the freport() command, you can make sure that you're not accidentally trying to perform operations on a file that's already in use.
