'fname' variable or function?

I am new to MATLAB and I am trying to run a code which I have not developed. It gives the following error:

??? Undefined function or variable 'fname'.

Error in ==> Rebuild2 at 8 for i=1:numel(fname)

Can someone please help me understand this error? Do I need to replace fname with an actual file name which might have data to be used? or do I have to pre-define this as a variable/function?

Any help would be appreciated!

Thanks!

Yes, fname is a common moniker for a filename string used in MATLAB. Since you give no details, I cannot guess what kind of file the code is expecting. Does the code have a help facility which might shed some light?

This is a common error when someone runs a function as a script. That is, running Rebuild2 via the interface (the Editor "play button"/F5) or at the command line

Rebuild2

when it should be called as a function

Rebuild2('foo.xls')
