-遍历矩阵，若出现元素与其左上角的元素不等的情况，返回 `false`。否则，遍历结束后返回 `true`。
+根据题目描述，托普利茨矩阵的特点是：矩阵中每个元素都与其左上角的元素相等。因此，我们只需要遍历矩阵中的每个元素，检查它是否与左上角的元素相等即可。

-### Solution 1
+### Solution 1: Single Traversal
+
+According to the problem description, the characteristic of a Toeplitz matrix is that each element is equal to the element in its upper left corner. Therefore, we only need to iterate through each element in the matrix and check if it is equal to the element in its upper left corner.
+
+The time complexity is $O(m \times n)$, where $m$ and $n$ are the number of rows and columns of the matrix, respectively. The space complexity is $O(1)$.
