MATLAB: How to convert a bit sequence to array

binary bit sequence

i have

key = 1234; bit_sequence = dec2bin(key);

how i convert bit_sequence = 10011010010 to A = [1 0 0 1 1 0 1 0 0 1 0]

a='10011010010'
out=a-'0'

Convert the key to binary. repmat() that as many times as will fit in a vector of length 1000. Fill the remainder of the 1000 with binary 0's.

key =1234;
bit_sequence = dec2bin(key)
new_bit_sequence=repmat(bit_sequence,1,50)
