Hi. I've got a 2 2500x1 vectors, and I've managed to find the x-cord of the local minimums. what I now need is a way to find the corresponding y value. I think my best bet is to find the 'number' of the minima (like how in [1, 5 ,7 ,2 , 3] 7 is the 3rd element, but I'm blanking on how to find that. In other words, I'm trying to find the element number of some number t in a vector T. (T is time, so I don't have to worry about any duplicate values).
Is there a way to do this? Or is there a better way to do this?

I figured it out. Use the find function. If t is the number you're looking for in a vector T, then the index of t is find(T==t).
