MATLAB: How to read a single column for specific data

loop

Hi,
How can I read this column just for specific data?
x=[1;2;3;4;5;6;7;8;9;10];
I just want to read 1,2,3 and 9, 10 and calculate some formula just for these data.
Could you please guide me how?

How do you know which data you want to "read"? Is it the 1st, 2nd, 3rd, 9th and 10th positions? If so then
x([1 2 3 9 10])
