if you make one file with this in it:

function ret = eserciziGlobal_Funzioni(x)

 global a; 

   ret=a;

endfunction

and name it  eserciziGlobal_Funzioni.m

and a second file with this in it

global a;

a=[1 12 30;3 5 50;6 3 2]

eserciziGlobal_Funzioni(3)

and name it testglobal.m

and then at the command prompt type

testglobal

It works for me.
