Decimal to binary as double type array, not string

Question

I have this so far:

data = 14
out = dec2bin(data, 4)

which gives:

out = 1110

But I want to get binary num

Answer 1

You're looking for de2bi with the 'left-msb' option.

data = 14
out = de2bi(data, 4,'left-msb')

Which requires the Communication Systems Toolbox though. Alternatively use your original approach with the fundamental dec2bin with the following addition:

data = 14
out = double( dec2bin(data, 4) ) - 48

---

out =

     1     1     1     0
