Hello everyone,
Actually, I have a curve as bellow. I am trying to find theb red points in my curve where there are sort of bumps or shoulders in my curve. I don't know how I can find them. I know that there are not peaks. maybe I should look for a function to find change in slope. dsc.jpg

Some of those "peaks" may be very difficult to capture but I'd start with findpeaks().
