Undefined variable when executing new object

Hello, I got an error when my function its trying to open a new object (window).

This is the code:

function SelectFiles
%SelectFiles is a function that open last records
%   

status = system('C:\BinaryFilesMatlab\SaveBinaryMatFile.exe 2 C:\Users\Kaf-125\Desktop\Versions\actual_gui3_patch2\file_name.mat m0_def_f0_fk');
if status == 0
    load('file_name.mat');
    res_opt = Results_with_opt(hObject,eventdata);
else
    error('Error al sustituir el archivo');
end
end

This is the error:

Undefined function or variable 'hObject'.

Error in SelectFiles (line 8)
    res_opt = Results_with_opt(hObject,eventdata);

Thank you in advance.

Your code calls Results_with_opt with two input arguments:

Results_with_opt(hObject,eventdata);

Neither of those input arguments are define in your code. What do you expect them to be?

What are you expecting hObject to be? Your function takes no input arguments and hObject is not defined inside the function.

Functions have closed scope - only variables passed in or defined in the workspace are visible within the function.

I am guessing that this is code in a GUI somewhere. If it is in a callback then you should have hObject as an input argument.

I solved it, just needed to call the function without arguments. Thank you.
