You can use bitand, e.g.,

>> bitand(1, 2.^(7:-1:0)) > 0

ans =

 0     0     0     0     0     0     0     1

Or

bitand(10, 2.^(7:-1:0)) > 0

ans =

 0     0     0     0     1     0     1     0

And, if you need to calculate many powers of two to include for an arbitrary number, you can use ceil(log2(theNumber))

Use str2num of the transposed array a:

a = dec2bin(1,4);

out = str2num(a')';

This way, each element of the string a is individually converted into a number.
