Convert Decimal to Binary Vector

Question

I need to convert a Decimal Number to a Binary Vector

For example, Something like this:

  length=de2bi(length_field,16);

Unfortunately, because of licensing, I cannot use this command. Is there any quick short technique for converting binary to a vector.

Here is what I am looking for,

If 
Data=12;
Bin_Vec=Binary_To_Vector(Data,6) should return me
Bin_Vec=[0 0 1 1 0 0]

Thanks

A single call to Matlab's built-in function dec2bin can achieve this:

binVec = dec2bin(data, nBits)-'0'
