arr2d = np.array([[1,2,3],[4,5,6]]) 这是一个Numpy的二维数组 利用索引,获得arr2d中的内容: arr2d[0]是[1,2,3],是一个一维数组,比arr2d二维数组降低了一个维度 arr2d[1]是[4,5,6],是一个一维数组,比arr2d二维数组降低了一个维度 arr2d[......
Theismatrixdocumentation states that a matrix"A matrix is a two-dimensional array that has a size of m-by-n, where m and n are nonnegative integers." Arrays have any number of dimensions, as far as I am concerned an array does not need to have pages, it can also be 2D (i.e. ...

.matmul()and the@operator perform matrix multiplication. They compute the dot product of two arrays. For 2D arrays, it’s equivalent to matrix multiplication, while for higher dimensions, it’s a sum product over the last axis of the first array and the second-to-last of the second array...
