function - How do I stop my switch statement from outputting the case in Matlab -

i trying write function can accomplish 3 tasks using menu statement in matlab, reason keeps outputting case number function answer.

    function fcn=jon2(x)       fcn=menu('choose function:','ceil','round','sign');       switch fcn        case 1          ceil(x)        case 2          round(x)        case 3          sign(x)      end     end 

when input 12 , select round, answers come out:

ans =

12 

ans =

 2 

you need use function properly, if defined as: fcn=jon2(x) should write each output using it:

... case 2     fcn = round(x); ... 

also, use ; suppress output command line...
