If x is the following string, I want to add a zero to the end of each sequence of zeros.
x='0110'
y=regexp(x,'[0+]','[0+]$0')
The result should be: x ='001100'

x = char(randi([0 1], 1, 20)+'0')
y = regexprep(x, '0+', '$00')
J Smith's answer doubles the length of each run of 0's in x. Mine adds one 0 to the end of each run of 0's. In the case where all the runs are of length 1 they are the same. They aren't the same when you have runs of length greater than 1.
