bit shifting and replacing in an array

I have an array A= [ 1 1 0] and W=11(binary). I want to replace the 1s by W (i.e 11) and 0s by 00. After that i want to shift and add the numbers like:

1 1 0

11 11 00

then, shift and add:

00

11

11

finally sum is: 10010

Kindly help me to doing this with matlab code. Thank you...
