convert int array to binary array

Question

Currently in matlab i have int array a=[8 3 2 1]; i want to convert it to binary array with four bits each.

for the above int array i would get the following binary array a binary=[1000 0011 0010 0001];

I tried the code given below:

binary = dec2bin([8 3 2 1],4)

I got answer as :

It is a column matrix. But I need a row matrix. [1000 0011 0010 0001]

can anyone help me????

thanks in advance.

If you don't need the leading zeros, you can use:

binary = str2num(dec2bin([8 3 2 1],4))'

This will give you:

binary =

        1000          11          10           1

If you want the leading zeros, you can use:

binary = cellstr(dec2bin([8 3 2 1],4))'

This will give you:

binary = 

    '1000'    '0011'    '0010'    '0001'

Edit: To take the complement of each bit of the array, you can use:

cmp = cellstr(dec2bin(bitcmp([8 3 2 1],4),4))'

You will get:

cmp = 

    '0111'    '1100'    '1101'    '1110'

@lara As in method #1, you can get the binary number without leading zeros.

But i need that leading zeros because i need to take the complement of each bit in a number.That is, if it is 0011 , then it changes to 1100.So i need 4 bit representation.
