Default is 0. order int, optional. How many points on each side to use for the comparison to consider comparator(n, n+x) to be True. mode str, optional. How the edges of the vector ...
Algorithm to locate local maxima - Stack Overflow
WebThe first major step to finding the relative extrema of a function f (x) is to find all critical points of the function f (x) on the domain -∞ < x < ∞. Critical points x = c are located where f (c) exists and either f ‘ (c) = 0 or f ‘ (c) is undefined. The steps for finding the critical points are as follows: Take the derivative of f (x ...

WebMar 20, 2012 · Your solution doesn't find all the local maxima, only a local maxima. Consider a matrix I * J only containing the value 5 in every cell, you will need to visit every all I * J cells to make sure that there is not a 4 or 6 in the matrix somewhere. – Seph Jan 31, 2013 at 8:02 it is the better approach to go with – Naresh Joshi Dec 7, 2024 at 6:06 WebFind the first derivative of a function f (x) and find the critical numbers. Then, find the second derivative of a function f (x) and put the critical numbers. If the value is negative, the function has relative maxima at that point, if the value is positive, the function has relative maxima at that point.
