Finding peaks in python
WebMar 27, 2024 · Find a peak element i.e. an element that is not smaller than its neighbors. Note: For corner elements, we need to consider only one neighbor. Example: Input: array []= {5, 10, 20, 15} Output: 20 Explanation: The element 20 has neighbors 10 and 15, both of them are less than 20. Input: array [] = {10, 20, 15, 2, 23, 90, 67} Output: 20 or 90 WebMar 11, 2024 · Peak finding and analysis on python 2024-04-21 11:17:17 1 400 python / matplotlib / scipy.
