- "the above script to be written as a function"   The code above is already a function. See Scripts vs. Functions
- "Why do I get that error?"   because "'fsw.Filter'" is not a legal name of a variable

translating a script into a function and executing it in the base workspace

function test()
fsw = System.IO.FileSystemWatcher();
fsw.Path = 'C:\Users\wolfgang';
fsw.Filter = 'test.csv';
fsw.EnableRaisingEvents = true;
listenerhandle = addlistener(fsw, 'Changed', @(~,~)testing1234(q,a));
%signature of importfcn is function importfcn(sender, eventargs)
%add a small delay in importfcn before reading the file as the event is raised
%to make sure that file modification is complete
end
I need the above script to be written as a function so that it gets executed in the base workspace. How can I do that?
yI use assignin('base','fsw',fsw) and it gets to the base workspace. However, somehow i get an error when i do assignin('base','fsw.Filter',fsw.Filter). Why do I get that error?

Let's say it's called test.m. Simply put this line at the beginning of the file to turn it from a script into a function
function test()

If you want them there then the functions should just return them and you call the function from a simple script.

At the risk of pointing out the obvious (and not having run your code), why not write it at the outset as:
function fsw = test()
and see if that does what you want.
EDIT —
It will return whatever variables you want it to return (here only ‘fsw’) to the workspace when the function completes and returns control to the calling script. See Create Functions in Files and related documentation for details.

Just type the name of the script on command line, then it will be executed.
