the signal is only in the positive half so zero crossing point is also the starting point for that cycle

Hi,if you have a signal like this
c =
Columns 1 through 15
0 1 2 3 4 5 6 7 8 9 10 0 1 2 3
Columns 16 through 22
4 5 6 7 8 9 10
using find you can find the indices where your vector(representing the signal's values) where the value is zero.
>> find(c==0)
ans =
1 12
