ok, so you have a list of filenames. Are these m-file scripts? data files you want to load and process in some way? .mat files that will bring in a bunch of variables when loaded? ...?

your filenames are strings, so there are a bunch of ways you could use a for loop appending that filename string to some other command like load, fopen, dlmread, etc.  See:

You can do a similar thing for file output once you have done whatever needs to be done. In you're loop you'll want to save data, where the save-as filename will somehow reflect the unique aspect of what was done, be it just appending the input filename, or something.

More specifics might produce more specific advice :)

​The filenames I fetched into a cell array using glob are data files in CSV format.  I want to run an Octave function separately on each of those data files (to process the data)​
​ ​and produce a separate output report file for each data file.

I know how to load a CSV file and process it with Octave.  What I don't know (and am asking for help - ideally an example code snippet) is how to extract the filenames from the cell array that glob created so that I can load and process them one at a time.

Thank you.
