如何在二维数组(矩阵)中找到局部极大值的索引？

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

    for i in range(rows):
        for j in range(cols):
            is_local_max = True
            current_value = matrix[i][j]

            # 检查上下左右和对角线方向的元素
            for x in range(max(0, i-1), min(i+2, rows)):
                for y in range(max(0, j-1), min(j+2, cols)):
                    if matrix[x][y] > current_value:
                        is_local_max = False
                        break

            if is_local_max:
                result.append((i, j))

    return result
