MATLAB: How to make the logical data homogene

vector

Hi all,
I have a vector logical data which varies between 0 and 1 in this way:
data = [0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 1 1 1 1 1 1 1 1 0 0 0 0];
the number of repetition of zeros and ones are irregular as seen above. My problem is that in some points some ONES are dropped out like this:
data = [0 0 0 0 0 0 0 0 0 0 0 1 1 1 0 1 1 1 1 1 1 0 1 1 0 0 0 0 0 0 1 1 1 1 0 1 1 1 0 0 0 0];
As you see elements number 15, 22 and 35 are exchanged from 1 to 0 in compared to the previous vector. I could fix it with a for loop asking to replace 0 to 1 every time there is a 0 between two 1s. But I was looking for some other way to avoid for loop.
I really appreciate any help.

As long as you never have a single isolated 1 surrounded by zeros that you want to keep, you can do it in a single line of code if you have the Signal Processing Toolbox:
fixedData = medfilt1(data)
