问题设A为任意n阶矩阵，下列为反对称矩阵的是( )

选项 A.A+AT B.A-AT C.AAT D.ATA

答案 B

解析由(A-AT)T=AT-A=-(A-AT)，则A-AT为反对称矩阵，故选B。

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
