16 paź 2024 · Transpose of a matrix is obtained by changing rows to columns and columns to rows. In other words, the transpose of A [ ] [ ] is obtained by changing A [i] [j] to A [j] [i]. Example of First Transpose of Matrix. Input: [ [ 1 , 2 , 3 ] , [ 4 , 5 , 6 ] , [ 7 , 8 , 9 ] ] Output: [ [ 1 , 4 , 7 ] , [ 2 , 5 , 8 ] , [ 3 , 6 , 9 ] ]
2 dni temu · Given a matrix of size n X m, find the transpose of the matrix. Transpose of a matrix is obtained by changing rows to columns and columns to rows. In other words, transpose of mat[n][m] is obtained by changing mat[i][j] to mat[j][i]. Example: Follow the given steps to solve the problem:
5 paź 2014 · This is a simple method that return an int[][] of the transposed matrix... public static int[][] transposeMatrix(int[][] matrix){ int m = matrix.length; int n = matrix[0].length; int[][] transposedMatrix = new int[n][m]; for(int x = 0; x < n; x++) { for(int y = 0; y < m; y++) { transposedMatrix[x][y] = matrix[y][x]; } } return transposedMatrix; }
Given a 2D integer array matrix, return the transpose of matrix. The transpose of a matrix is the matrix flipped over its main diagonal, switching the matrix's row and column indices. Example 1: Input: matrix = [[1,2,3],[4,5,6],[7,8,9]] Output: [[1,4,7],[2,5,8],[3,6,9]] Example 2: Input: matrix = [[1,2,3],[4,5,6]] Output: [[1,4],[2,5],[3,6 ...
9 maj 2023 · Transpose of a matrix is obtained by changing rows to columns and columns to rows. In other words, transpose of A[][] is obtained by changing A[i][j] to A[j][i]. For Square Matrix: The below program finds transpose of A[][] and stores the result in B[][], we can change N for different dimension.
10 lut 2012 · Is it possible to transpose a (m,n) matrix in-place, giving that the matrix is represented as a single array of size m*n? The usual algorithm . transpose(Matrix mat,int rows, int cols ){ //construction step Matrix tmat; for(int i=0;i<rows;i++){ for(int j=0;j<cols;j++){ tmat[j][i] = mat[i][j]; } } }
