Binary Bit Masking

What is the easiest way to bit mask a 16 bit binary value to decode different fields (2 bit, 4 bit, etc) with it? Thanks

Answer 1

[Fangjun Jiang]

bitand(), bitor(),

Answer 2

[Walter Roberson]

You could use bitand() and bitshift() too. Or just bitget().

Watch out for the bit numbering order that MATLAB uses.

Thanks Walter. But with bitget() I can't get multiple bits just one? Correct?

[Fangjun Jiang]

You can get multiple bits.

bitget(7,1:3)

[thinnawat chumpuwiset]

i'm still confuse about bitget(), can you describe more detail?

Answer 3

>> dec2bin(7,8)

ans =

      '00000111'

>> bitget(7,1:8)

ans =

       1     1     1     0     0     0     0     0
