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.
