WebThe second derivative may be used to determine local extrema of a function under certain conditions. If a function has a critical point for which f′(x) = 0 and the second derivative is positive at this point, then f has a local minimum here. If, however, the function has a critical point for which f′(x) = 0 and the second derivative is negative at this point, then f has local … WebApr 13, 2024 · Direct mapping like this is what you'd use when you have an actual indexed image (e.g. a GIF file). Scaled mapping is what you might be used to if you just want to display a single-channel image or data in pseudocolor with imagesc() or imshow(). While ind2rgb() alone works for direct mapping, the attached function does the latter. WebStep 1: Finding f' (x) f ′(x) To find the relative extremum points of f f, we must use f' f ′.
