This example (in R2014a) might be useful and here is a sample code. You need to create waitbar before for loop and update inside the loop.

% Create initial waitbar
f = waitbar(0, '', 'CreateCancelBtn','setappdata(gcbf,''canceling'',1)');

for j = 1:length(parentDir)
    matchList{j} = [matchList{j}; names(endIdx == strLen & endIdx > 0)'];
        
    % In order to avoid "invalid interpreter syntax" warning
    folderNameWithValid = strrep(parentDir{j}, "\", "\\");
    
    % Update waitbar and message
    waitbar(j/length(parentDir), f, sprintf('Reading %s', folderNameWithValid))    
end

% Delete waitbar
delete(f)
