Python 教程之 Numpy(2)—— 数组 Numpy中的N维数组(ndarray) Numpy 中的数组是一个元素表(通常是数字),所有元素类型相同,由正整数元组索引。在 Numpy 中,数组的维数称为数组的秩。给出数组沿每个维的大小的整数元组称为数组的形状。Numpy 中的数组类称为ndarray。Numpy 数组中的元素可以使用方括号访问,并且...
numpy.matmul()计算两个数组的矩阵乘积。 示例 importnumpy as np a= np.array([[1,2,3],[4,5,6],[7,8,9]]) b= np.array([[23,23,12],[2,1,2],[7,8,9]]) mul=np.matmul(a,b)print(mul) 1. 2. 3. 4. 5. 输出 [[ 48 49 43] ...
