Sounds like homework.

How do I get help on homework questions on MATLAB Answers? - MATLAB Answers - MATLAB Central

Hint:

columnIndexes = 1 : 16

columnIndexes = 1×16

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

out = columnIndexes(1 : 2 : end)

out = 1×8

1 3 5 7 9 11 13 15

That should be a good enough hint for you to do your homework.
