What do you think "x(ix)" represents?

Haha. I guessed I overlooked that. Thanks for pointing out my mistake. Still a noob >.<
I tried using your solution but the value it gives me is wrong from my graph. Is there any reason to why that happens?

I merely replaced your y with w which is the graph i'm using as an input. Could you like explain what does the -1 and 1 do in this sentence?
[ym,ix] = find(sign(diff(w))==-1,1);

Is it because of the line and plot difference? Thanks alot.
