How to detect a real-time signal's local maxima and minima?
6 views (last 30 days)
Most toolkits require all data before detection of maxima and minima happens. What if I have a real-time signal "feed" and I need a detector that measures whether the gradient slightly behind the data point at current time? So this is a gradient checking function to determine if the next point belongs to a local maxima or minima region.
Does anyone know a function or toolkit that is capable of doing this?
