但是在一定的规则下,numpy可以帮你进行broadcast。虽然我一开始对这种特性不以为然,但是后来发现,它对写vectorized的代码是非常有帮助的,而且往往计算效率会更高(因为所谓broadcast只是概念上的,真正运算的时候不会真占用那么多的空间) 当我们说一个标量或者向量要进行broadcast的时候,一定是指进行elementwise的操作,不会...
You can use np.multiply to multiply two same-sized arrays together. This computes something calledthe Hadamard product. In the Hadamard product, the two inputs have the same shape, and the output contains the element-wise product of each of the input values. You can also use np.multiply to...
Python code to multiply a NumPy array with a scalar value# Import numpy import numpy as np # Creating two numpy arrays arr1 = np.array([10, 20, 30]) arr2 = np.array([30, 20, 20]) # Display original arrays print("Original Array 1:\n",arr1,"\n") print("Original Array 2:\...
