MATLAB: Adding zeros to a number

Question

So I have this number 0 1 0 1 0 it is only 5 bits long but I want to add all zeros to the end of the number to make it 23 bits long. I have played around with this some but I cannot seem to get it to add zeros to the end of the number.

Thanks

Answer 1

A = [0 1 0 1 0];
A = [A, zeros(1, 23-length(A))];
