so, if i use:
index =: indexVector i. (todayno 2007 3 9)
$ index
returns nothing
#index
1
index - i. -days
164 165 166 167 168 169 170 171 172 173 174 175 176 177 178
Which is what I want without using (+/ index).
My problem was the way in which I was generating the value for index. The
rank was not proper for using with i.
Still confused, but a little happier.
Nabble is great. I Raul Millers approaches to finding an index produced
what I needed.
