检查矩阵行是否等于R中的向量，进行向量化

I'm very surprised this question has not been asked, maybe the answer will clear up why. I want to compare rows of a matrix to a vector and return whether the row == the vector everywhere.

Suppose there are many rows as well, so I would like to avoid repping the vector.I'm very surprised this question has not been a
