Unfortunately not. I've written the following short demo/test case to 
illustrate the problem:

##############################################

data = [ 0,0,0; 256,0,0; 0,256,0; 256,256,0; 128,128,5 ];

function foo()
  global data;
  data
endfunction

foo(); # outputs data = [](0x0)

data   # outputs full matrix

##############################################

As you can see the global matrix 'data' is not visible within foo() even 
if global data added to foo ...

:(
