Since you're only dealing with integers between 0 and 100, if you change the first line to:

a1 = int8(rand(225).*100);

you will significantly decrease the memory required. again, later, 

you can use the 'whos' command to see the variable memory usage.
 cc      50625x50624             2562840000  int8
  g       50625x50624             5125680000  uint16

this gets to your next line which produces an error:

>> g1=g>=b&g<=c;
error: mx_el_ge: nonconformant arguments (op1 is 50625x50624, op2 is 50624x1)

so you should re-examine what you're trying to do there.
