Hello,
I'm trying to run the beginning of a script that was sent to me:
function [ FList ] = ReadFileNames(DataFolder)
DirContents=dir(DataFolder);
FList=[];
DataFolder is the name of the folder in which all my data is held. When I click the Run button I receive:
ReadFileNames(DataFolder)
Unrecognized function or variable 'DataFolder'.
And I'm not sure why?
Any help is much appreciated. Thank you.

Where is DataFolder defined? If you haven't defined it, you will need to do so.

Hi DGM,
I defined DataFolder, but still receive an error message:
function [ FList ] = ReadFileNames(DataFolder)
↑
Error: Function definition are not supported in this context. Functions can only be created as local or
nested functions in code files.

Ran in:
Tell the program what your data folder is
DataFolder = 'C:\';
ReadFileNames(DataFolder)
ans = []
function [ FList ] = ReadFileNames(DataFolder)
DirContents=dir(DataFolder);
FList=[];
end

If you're using a version older than R2016b, you can't have functions defined in a script. You didn't specify what version you're using, so I'll just throw that out there.
