For each query point Q in QUERY, this function finds the first INDEX that satisfies Q >= LOWER(INDEX) && Q < UPPER(INDEX). This is a vectorized solution to the problem of finding the interval that bounds one or more points, where there may be gaps between each interval. Histcounts requires intervals to be contiguous, which is not always desirable.

Example:

% 0.5 second gap between intervals

t1 = 1:10;

t2 = 1.5:10.5;

query = [-1 1.25 1.75 4.25 15]; % only 2nd & 4th values are inside an interval

idx = findinterval(t1, t2, query)

% idx = [0 1 0 4 0]
