[Array]Find Peak Element A peak element is an element that is greater than its neighbors. Given an input array where num[i] ≠ num[i+1], find a peak element and return its index. The array may contain multiple peaks, in that case return the index to any one of the peaks is fine....

[LintCode] Find Peak Element 求数组的峰值 There is an integer array which has the following features:The numbers in adjacent positions are different. A[0] < A[1] && A[A.length - 2] > A[A.length - 1].We define a position P is a peek if:...
第二种是升序数组,如[1,2,3,4,5],Peak Element为 4;遍历到终点i = 4发现都不满足nums[i] > nums[i+1],因此数组中最后一个元素为Peak Element,返回4。 第三种是Peak Element在数组中间任意位置,如[1,3,2,4,5], Peak Element为 1;遍历到i = 1时满足nums[i] > nums[i+1],因此返回1。

As stated in the documentation, scipy.signal.find_peaks works for 1D signals. There are many attempts of similar function for 2D arrays, such as https://stackoverflow.com/questions/3684484/peak-detection-in-a-2d-array, https://stackoverf...
The peaks and troughs are notable events in this data set. To identify the peaks and troughs in the smoothed data, use the islocalmax and islocalmin functions. Then get the date and the value of the excess LOD for each peak and trough. Create a categorical array with two types, peak...
How the code works: In theory, each peak is a smooth point spread function (SPF), like a Gaussian of some size, etc. In reality, there is always noise, such as "salt and pepper" noise, which typically has a 1-pixel variation. Because the peak's PSF is assumed to be larger than ...
