dim.

Accurately computes the logarithm of the sum of exponentials across rows or columns.

array

High-performing functions operating on rows and columns of matrices, e.g. col / rowMedians(), col / rowRanks(), and col / rowSds().  Functions optimized per data type and for subsetted calculations such that both memory usage and processing time is minimized.  There are also optimized vector-based methods, e.g. binMeans(), madDiff() and weightedMedian().

matrixStats

Functions that Apply to Rows and Columns of Matrices (and to Vectors)

rowLogSumExps function

These methods are implemented in native code and have been optimized
  for speed and memory.
