numpy.dot() 对于两个一维的数组,计算的是这两个数组对应下标元素的乘积和(数学上称之为内积);对于二维数组,计算的是两个数组的矩阵乘积;对于多维数组,它的通用 ... ... <看更多>
The @ operator calls the array's matmul method, not dot. This method is also present in the API as the function np.matmul. ... <看更多>
print(np.dot(a1,a2)) 20. argmin 取出矩陣元素最小值的index, argmax 取出矩陣元素最大值的index. >>> a = np.arange(2,14).reshape((3,4)) >>> print(a) [[ 2 3 4 ... ... <看更多>
