如何将二维数组中的元素与其他元素进行比较？

def compare_elements(matrix):
    rows = len(matrix)
    cols = len(matrix[0])

    for i in range(rows):
        for j in range(cols):
            current_element = matrix[i][j]
            for k in range(rows):
                for l in range(cols):
                    if i != k or j != l:
                        other_element = matrix[k][l]
                        # 进行比较操作，这里以比较大小为例
                        if current_element > other_element:
                            print(f"{current_element} 大于 {other_element}")
                        elif current_element < other_element:
                            print(f"{current_element} 小于 {other_element}")
                        else:
                            print(f"{current_element} 等于 {other_element}")

# 示例二维数组
matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
compare_elements(matrix)
