Python program to get the index of a maximum element in a NumPy array along one axis# Import numpy import numpy as np # Creating a numpy array arr = np.array([1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8,1,2,3,4,5,6,7,8]) # Display original array print("Orig...
To find the index of the maximum element in an array, we usethenumpy.argmax()function. This function works with a list and can return the index of the maximum element. Example: importnumpyasnp lst=[1,4,8,9,-1]i=np.argmax(lst)print(i) ...
Example 1: Max & Min of All Values in NumPy ArrayIn this example, I’ll illustrate how to get the minima and maxima of all values in a NumPy array.To calculate the maximum value, we can use the np.max function as shown below…print(np.max(my_array)) # Get max of all array ...
函数的官方定义为:"Find peaks in an image as coordinate list or boolean mask. Peaks are the local maxima in a region of `2 * min_distance + 1` (i.e. peaks are separated by at least `min_distance`). If both `threshold_abs` and `threshold_rel` are provided, the maximum of the tw...
