I have a logical vector, and i want to add elements after the 0's and after the 1's, but a different element after the 0's than the 1's. How do I do this.

Here is one way
% Original logical vector input
L = logical([1 0 1 1 0]);
% The numbers to be inserted
oneNum = 6;
zeroNum = 3;
output = [L; zeroNum*ones(1,length(L))];
output(2,L==1) = oneNum;
output = output(:)'
output = 1×10
1 6 0 3 1 6 1 6 0 3

What if I want to add instead of 6, 666666, so like multiple in the place.

If it is always the same number of repeats, then it is a straightforward extension of the above:
% Original logical vector input
L = logical([1 0 1 1 0]);
% The numbers to be inserted
oneNum = 6;
zeroNum = 3;
% Number of repetitions
repeats = 4;
output = [L; zeroNum*ones(repeats,length(L))];
output(2:end,L==1) = oneNum;
output = output(:)'
output = 1×25
1 6 6 6 6 0 3 3 3 3 1 6 6 6 6 1 6 6 6 6 0 3 3 3 3
