How can I suppress the 'ans' output?

When my code looks like this

function [ z ] = summie( x,y )

z=x+y;
disp(['The summie is: ', num2str(z)])

end

and I typ in the command window for example

summie(1,2)

This is displayed:

The summie is: 3

ans =

       3

Is there a way to suppress the 'ans' output, so that only

The summie is: 3

is displayed?

Use this function :-

    function  summie( x,y )
    z=x+y;
    disp(['The summie is: ', num2str(z)])
    end

That is, do not send 'z' as output. In other words,return type of your function should be 'void' to suppress the 'ans' output. Search this PDF on internet –

This works perfectly. Thanks a lot Matt!

--EDIT: oops, I meant Sagar indeed... Therefore: thanks a lot Sagar! ;) But thank you for your help too Matt. Why can't I accept 2 answers? Know what, I'll give you my vote!

I think you meant to thank Sagar. However, consider also my solution with varargout. It is similar to Sagar's solution, but allows you to continue to have an optional output argument.

Add a semicolon to the end of the function call

 sum(1,2);

Incidentally, it is a bad idea to call your function "sum", since this will conflict with MATLAB's native SUM command.

Yes, of course, but that isn't related to my question. The function I'm using here is only an example of a possible function. But I'll change the function's name if you insist.

Secondly, I'd like to change something in my function code itself (add some extra code or something) to suppress that the 'ans' is displayed.

    function varargout = summie( x,y )

        z=x+y;
        disp(['The summie is: ', num2str(z)])

        if nargout
            varargout{1}=z;
        end

    end

This works perfectly aswell! Thanks Matt!
