WebIf your coordinates are the set of points { x, f }, then run a three-point median filter m=MedianFilter [f,1] and compare function values f to filtered values m. The function f has a local maximum at a point where f > m. A local minimum occurs where f < m. On slopes, the median equals the function value.
