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
