Hi All,
I have created a executable using the application complier.
The function requires the input file path
function main(filepath)
I am not sure how to pass the file path as an input argument to the executable generated using the about funciton.
I tried
!main 'I:\project\task'
but this is not working.
Suggestions will be really helpful.

"This is no working" is too lean to explain, what happens. Prefer to mention, what you observe. This helps to solve your problem.

Sorry about missing out on the error details.
function main(TASK_DIR)
tbl = readtable(fullfile(TASK_DIR,'input.xlsx'));
I see the following error message
>> !main char(task_dir)
ans =
'char(task_dir)'
....read data
Error using readtable (line 318)
Unable to find or open 'char(task_dir)\input.xlsx'. Check the path and filename or file permissions.

You're using Matlab syntax to define a char vector, but that is something that will happen automatically.
You can experiment with this tester function:
function main(varargin)
for n=1:nargin
fprintf('input number %d has class %s and contains this:\n',n,class(varargin{n}))
disp(varargin{n})
fprintf('\n')
end
end
To avoid syntax error caused by DOS itself you should consider
!main "I:\project\task"
You can test the effect quickly by using ECHO so you get immediate feedback about any syntax issues.
Edit after your comment to Jan:
You probably want this:
[status,response]=dos(['main ' taskdir]);
That will send the char contained in taskdir as the argument to the function main.

I had tried the last option which didn't work for me.
The second suggestion works great! Thanks a lot.
