A matrix is Toeplitz if every diagonal from top-left to bottom-right has the same element. Now given an M x N matrix, return True if and only if the matrix is Toeplitz. Example 1: Input: matrix = [   [1,2,3,4],   [5,1,2,3],   [9,5,1,2] ] Output: True…
Given a matrix A, return the transpose of A. 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]] Ex…

Question 766. Toeplitz Matrix Solution 题目大意: 矩阵从每条左上到右下对角线上的数都相等就返回true否则返回false 思路: 遍历每一行[i,j]与[i+1,j+1]是否相等,不等就返回false,相等就接着遍历,都遍历完了就返回true Java实现: public boolean isToeplitzMatrix(int[][] matrix) { int i = 0; while (i < matrix.length - 1) { int j =…
题目要求 A matrix is Toeplitz if every diagonal from top-left to bottom-right has the same element. Now given an M x N matrix, return True if and only if the matrix is Toeplitz. 题目分析及思路 给定一个M x N的矩阵,判断这个矩阵是不是Toeplitz.符合条件的矩阵应满足从左上到右下的每条对角线上的元素都相同.我们可以发现同…

In MATLAB, there is a very useful function called 'reshape', which can reshape a matrix into a new one with different size but keep its original data. You're given a matrix represented by a two-dimensional array, and two positive integers r and c rep…
