Re: Maximum of the consecutive events

Hi Debasish,

In your values below, you have "6" as the maximum for "2,6,4,7,3,6".
Shouldn't this be "7"?

Anyway, try the attached script. It uses "ind" to get the indices of
the missing values, and then
uses this information to determine what consecutive non-missing
values you have.
