Answer 1

You can use the BITGET function:

abinary = [bitget(a,4); ...  %# Get bit 4 for each number
           bitget(a,3); ...  %# Get bit 3 for each number
           bitget(a,2); ...  %# Get bit 2 for each number
           bitget(a,1)];     %# Get bit 1 for each number
abinary = abinary(:)';      %'# Make it a 1-by-20 array
