你可以使用range和来获得最小值和最大值之间的差异，diff并选择大于2的行。
A[apply(A, 1, function(x) diff(range(x))) > 2, ]
# [,1] [,2] [,3] [,4] [,5]
#[1,] 1 2 3 4 5
#[2,] 2 3 6 4 3
对于更大的矩阵，你还可以使用中的rowRanges函数matrixStats。
mat <- matrixStats::rowRanges(A)
A[mat[, 2] - mat[, 1] > 2, ]

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
