You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: icatb_executeCallback.m
    path of file: ./repos/bspm/thirdparty/MIALAB/GroupICATv4.0a/icatb/icatb_helper_functions
    
    the code of the file until where you have to start completion: function icatb_executeCallback(objHandle)
% Execute the function callback using feval function as it takes into
% account the sub functions and any function overloading mechanism

% get the callback property for the object
objCallback = get(objHandle, 'callback');

if ~isempty(objCallback)

    
function icatb_executeCallback(objHandle)
% Execute the function callback using feval function as it takes into
% account the sub functions and any function overloading mechanism

% get the callback property for the object
objCallback = get(objHandle, 'callback');

if ~isempty(objCallback)
    
    % Execute the callback using feval
    if length(objCallback) > 1
        feval(objCallback{1}, objHandle, [], objCallback{2:end
