----------------------------------------
Summary: Elementwise analogues of scala.math functions for tensor
types
Key: MAHOUT-1727
URL: https://issues.apache.org/jira/browse/MAHOUT-1727
Project: Mahout
Issue Type: Improvement
Reporter: Dmitriy Lyubimov
Assignee: Dmitriy Lyubimov
Fix For: 0.10.2
what we mean here:
log(5)
vlog(vec)
mlog(mxA)
dlog(drmA)
in R, all these variants are enacted by single function log(x). Unfortunately,
we cannot overload standard functions since they are defined in another package
and Scala would allow such an overload.
Hence, notation conventions:
vector functions are prepended by 'v': vlog, vabs...
in-core matrix functions are prepended by 'm': mlog, mabs...
DRM functions are prepended by 'd' (for distributed): dlog, dabs...
