Find number in vector

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 ?

Answer 1

find(A>3,1)

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.

Try this:

A = [1,2,3,40,50,60];
index = find(A > 3, 1, 'first')

index = 4

theValueThere = A(index)

theValueThere = 40
