Merge two binary vectors

Question

I need to combine the binary representation of 6 and 7 together:

bin1 =  fliplr(de2bi(6));
bin2 =  fliplr(de2bi(7));

bin1 =

     1     1     0


bin2 =

     1     1     1

after the combination the number should be

bin3 = 110111

Does anyone have any idea on how to do this?

As suggested you can just concatenate them

bin3 = [bin1, bin2]

However, if you really want them packed together without spaces you can do it like this:

bin3 = num2str([bin1, bin2]);
bin3 = bin3(bin3 ~= ' ')

If you want to turn them in to a number now you can use str2num()

Even shorter: num2str(bin3, '%d')
