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

2
rowLogSumExps(lx, na.rm=FALSE, ...)
colLogSumExps(lx, na.rm=FALSE, ...)
Arguments
lx
A numeric NxK matrix.
Typically lx are log(x) values.
na.rm
If TRUE, any missing values are ignored, otherwise not.
...
Not used.
Value
A numeric vector of length N (K).
Benchmarking
These methods are implemented in native code and have been optimized
for speed and memory.
Author(s)
Native implementation by Henrik Bengtsson.
Original R code by Nakayama ??? (Japan).
