The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix. Example 1: Input:[[1,2,3],[4,5,6],[7,8,9]] Output:[[1,4,7],[2,5,8],[3,6,9]] Example 2: Input:[[1,2,3],[4,5,6]] Output:[[1,4],[...

numpy包含两种基本的数据类型:数组(array)和矩阵(matrix)。无论是数组,还是矩阵,都由同种元素组成。 下面是测试程序: # coding:utf-8 import numpy as np # print(dir(np)) M = 3 #---Matrix--- A = np.matrix(np.random.rand(M,M)) # 随机数矩阵 print('原矩阵:'...

NumPy Matrix transpose() Python numpy module is mostly used to work with arrays in Python. We can use the transpose() function to get the transpose of an array. import numpy as np arr1 = np.array([[1, 2, 3], [4, 5, 6]]) print(f'Original Array:\n{arr1}') arr1_transpose ...
The result is a series oftuples, where each tuple contains the corresponding elements from the rows of the original matrix. Example 3: Rearrange 2D List Using NumPy In this final example, we will use thetranspose() functionfrom Python’sNumPy libraryto transpose the 2D list. ...
