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)

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);
