Hi,
I would like to select only one value every four in an array. For instance, given an array [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16], I obtain
[4 8 12 16]. Are there simple commands to do this?

Ran in:
a = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16]
a = 1×16
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
b = a(4:4:16)
b = 1×4
4 8 12 16
