Intersect 2 arrays to find a position

I have 3 vectors like these:

hour=[8 8 8 9 9 9]

Minute=[15 30 45 15 30 45]

V=[10 6 5 4 3 11]

How do I intersect the first 2 in order to find the position to extract the value from de V vector.

For example: I want to extract all values starting at 8.45h

[Azzi Abdelmalek]

hour=[8 8 8 9 9 9]
Minute=[15 30 45 15 30 45]
V=[10 6 5 4 3 11]
s='8.45'
ii=cellfun(@str2num,strsplit(s,'.'))
id=find(hour==ii(1) & Minute==ii(2))
out=V(id:end)

A simplification:

ii = sscanf(s, '%d.%d')

Thank you Azzi and Jan! You helped a lot :)

I'm not sure if I'm clear on the question, but is this what you have in mind?:

V(hour+Minute/60 >= 8.75)
