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);
