  Mi=M(i); 
  MBi=['0000',dec2bin(hex2dec(Mi))]; 
  MBi=MBi(end-3:end); 
  MBi=[str2num(MBi(1)),str2num(MBi(2)),str2num(MBi(3)),str2num(MBi(4))];

Did you have a look at the docs:

hex2dec

dec2bin

str2num

matrix indexing

They pretty much explain it. If you still don't understand the whole thing, post back with what you do understand and where you're getting stuck. You might also find;

Decimal Number

Binary Number

Hexadecimal Number

helpful.

I'm disappointed that I can't add the the link markup into code segments. It would have been more fun that way.
