Accepted answer
for K = numel(YourArray): -1 : 1
if (K / 5) == fix(K / 5)
YourArray(K) = [];
end
end
There are definitely easier ways, but your question sounds like an assignment.

x - your array
out = x(rem(x,5) ~= 0)

It is the _index_ whose value is a multiple of 5 that is to be affected, not according to the value of the array.
It seems likely to me that this task is homework, so I have refrained from giving the very short and simple solution.
