You may already know how to find the logical indices of the elements of a vector that meet your criteria.

This exercise is for finding the index of indices that meet your criteria. The difference is this:

vec = [11 22 33 44]; thresh = 25; vi = (vec > thresh)

vi =

0 0 1 1

What we are looking for now is how to get the values

x =

3 4

Because those are the indices where the binary comparison is true.

Check out find.

Given a vector, vec, return the indices where vec is greater than scalar, thresh.
