编写一函数,将一个3×3矩阵转置

以下是Python语言的实现：

def transpose(matrix):
    """
    将一个3×3矩阵转置
    """
    transposed_matrix = []
    for j in range(len(matrix[0])):
        temp = []
        for i in range(len(matrix)):
            temp.append(matrix[i][j])
        transposed_matrix.append(temp)
    return transposed_matrix

使用示例：

matrix = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
transposed_matrix = transpose(matrix)
print(transposed_matrix)

输出结果为：

[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
