Given a matrixA, return the transpose ofA. The transpose of a matrix is the matrix flipped over it's main diagonal, switching the row and column indices of the matrix.(一矩阵A,返回其转置) 【思路】 直接处理,A[i][j]的值赋值给
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],[...
So if X is a 3x2 matrix, X' will be a 2x3 matrix. Here are a couple of ways to accomplish this in Python. Matrix Transpose using Nested Loop # Program to transpose a matrix using a nested loop X = [[12,7], [4 ,5], [3 ,8]] result = [[0,0,0], [0,0,0]] # ...
def transpose2(matrix): transposed = [] for i in range(len(matrix[0])): transposed.append([row[i] for row in matrix]) return transposed def transpose3(matrix): transposed = [] for i in range(len(matrix[0])): transposed_row = [] for row in matrix: transposed_row.append(row[i]...
矩阵转置题目:编写一个函数,将一个二维矩阵转置。解答:```pythondef transpose(matrix):return [list(i) for i in zi
python编程算法 这一题我的思路非常的暴力,就是把每一行和每一列的元素全部记录下来,然后比较一下求个积即可。 codename_cys 2022/08/23 2470 [Leetcode][python]Spiral Matrix/Spiral Matrix II/螺旋矩阵/螺旋矩阵 II 编程算法 输入: matrix = [ [1, 2, 3], [4, 5, 6], [7, 8, 9] ] 输出: ...
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. ...
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 ...
As you can see, we rotated our data matrix. You can also see that the row names of the original data frame are now the column names and the column names are now the row names. Video & Further Resources Do you need more information on the R code of this tutorial? Then you could wa...
