MATLAB: Can I supress an ‘ans’ output without making a void function

ans suppressmatlab function

function[ Hours Minutes Seconds Message ] = TimeConversion(TotalSeconds);
Hours = floor(TotalSeconds/3600);
Minutes = floor((TotalSeconds-(Hours*3600))/60);
Seconds = TotalSeconds-Hours*3600-Minutes*60;
Message = [num2str(TotalSeconds) ' Second(s) is equal to '… num2str(Hours) ' hour(s), ' … num2str(Minutes) ' minute(s), and ' … num2str(Seconds) ' second(s).'];
disp(Message);
end
When I Run this code:
>> TimeConversion(51624)
51624 Second(s) is equal to 14 hour(s), 20 minute(s), and 24 second(s).
ans =
    14
Is there a way to suppress the ans?(which is obviously referencing 'Hours'), but keep the array in the function output for things such as: "[out1, out3] = TimeConversion(82000)"

Best Answer

Yes, test to see if nargout is 0 and if it is don't assign anything to any of the outputs. You'll have to rejig your code to use temporary variables for hours, minute, seconds and message:
function [Hours, Minutes, Seconds, Message] = TimeConversion(TotalSeconds);
  h = floor(TotalSeconds/3600);
  m = floor((TotalSeconds-(Hours*3600))/60);
  s = TotalSeconds-Hours*3600-Minutes*60;
  msg = sprintf('%d Seconds is equal to %d hour(s), %d minute(s), and %d second(s).', TotalSeconds, h, m, s);
  disp(msg);
  if nargout > 0
    Hours = h;
    Minutes = m;
    Seconds = s;
    Message = msg;
  end
end
