我有一个列表,其中每个元素是一个5*5矩阵.例如
[[1]]
V1 V2 V3 V4 V5
[1,] 0.000000 46.973700 21.453500 338.547000 10.401600
[2,] 43.020500 0.000000 130.652000 840.526000 56.363700
[3,] 12.605600 173.238000 0.000000 642.075000 19.628100
[4,] 217.946000 626.368000 481.329000 0.000000 642.341000
[5,] 217.946000 626.368000 481.329000 0.000000 642.341000

如何使用类似应用的函数对矩阵[1]到[n]求和,并返回一个5*5矩阵作为结果(每个元素是列表中每个矩阵中相应元素的总和)？
