Let’s say I have this vector: A = [1,2,3,4,5,6] and I want to know when did my vector went above 3. Like I want to know the value that made my vector go above 3. So I’m interested in the value “4” not 5 or 6. Is there is a code that can help me ?

This gives the index, not the value. To see the value, see my answer below where I give both the index and the value of the vector at that index.

Ran in:
Try this:
A = [1,2,3,40,50,60];
index = find(A > 3, 1, 'first')
index = 4
theValueThere = A(index)
theValueThere = 40
