Example 1: Sum of All Values in NumPy ArrayThe following code demonstrates how to calculate the sum of all elements in a NumPy array.For this task, we can apply the sum function of the NumPy library as shown below:print(np.sum(my_array)) # Get sum of all array values # 21...
array([ 4, 16, 25]) 1. 2. 按位异或 >>> a^2 array([0, 6, 7]) 1. 2. 指数运算 >>> numpy.exp(a) array([ 7.3890561 , 54.59815003, 148.4131591 ]) 1. 2. 真正的矩阵乘法需要用numpy.dot(A,B) >>> a=numpy.array([2,4,5]) >>> b=numpy.array([[1],[1],[1]]) >>> ...
1. Sum of All the Elements in the Array If we pass only the array in the sum() function, it’s flattened and the sum of all the elements is returned. import numpy as np array1 = np.array( [[1, 2], [3, 4], [5, 6]]) total = np.sum(array1) print(f'Sum of all the ...
输出:array([-0.27357369, 0.07827272, 1.2756936 , 0.06018418, 0.20406572, -1.5830942 , -1.49025786, 0.20409636]) y 输出:array([ 1.28998788, 1.94645189, 0.13716615, -0.70732559, -0.32622699, 0.07944005, -0.71163361, 1.12823112]) np.maximum(x, y) #返回元素级最大值 输出:array([ 1.28998788, 1.94645189...
