How to get matrix data from function ,anyone help me

Z=[ 1 3 4 ;5 3 1;3 3 3];
a=1;
Qa=example(a,Z);
ss=Qa(1)+Qa(2); %=====> I CAN'T get both matrix data a+Z and a*Z  

%%
%%%my function building as such   
function dBB=example(a,Z)               
dBB(1)= Z+Z;                                    
dBB(2)=Z+Z+Z+Z+Z;                                    
%%%%%%

Not sure what the real question is. Maybe this does what you want?

function [apZ,atZ]=example(a,Z)               
apZ = a + Z;                                    
atZ = a * Z;                                    
end

and you would call it like this

[x,y] = example(a,Z);

Thank you ,James

I wnat to perform the following operations in the main program

answer = sqar ( apZ.^2 +atZ.^2)

[Walter Roberson]

[apZ, atZ] = example(a,Z);
answer = sqrt(apZ.^2 + atZ.^2);
