You can do this if there is a pattern:

X = [0.081,0.082,0.089,0.091,0.095,0.098,0.13,0.15,0.18,0.21,0.25,0.31];
x = [X(1:3:end) X(end)]

In your case the pattern does not get the last value, because it does not meet the pattern given for all other values. So the

X(end)

statement is needed to complete x as you wanted it to have.
