To find the maximum element in a NumPy array, we can use the numpy.amax() function. This function returns the maximum element from an array along a specified axis. import numpy as np # Create a NumPy array x = np.array([1, 2, 3, 4, 5]) # Find the maximum element from the arr...
Using NumPy argmax() to Find the Index of the Maximum Element in a 2D Array Let’sreshape the NumPy arrayarray_1into a two-dimensional array with two rows and four columns. array_2=array_1.reshape(2,4)print(array_2)# Output[[1572][10984]] Copy For a two-dimensional array, axis 0...

numpy.argmax()函数 numpy.argmax()函数是numpy中用来查找数组中最大元素的函数,它返回的是最大元素在数组中的下标。 import numpy as np arr = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) maxIndex = np.argmax(arr) print("Max element index:", maxIndex) # Output: # Max eleme...
The max() method returns the largest element of an array along an axis. The max() method returns the largest element of an array along an axis. Example import numpy as np array1 = np.array([10, 12, 14, 11, 5]) # return the largest element maxValue= np.ma
Finding the min/max excluding zeros in a numpy arrayFor this purpose, we will first return all the non-zero elements of the numpy array using numpy.nonzero(arr) command and then we will apply numpy.min() and numpy.max() methods on this....
