Follow-up Comment #2, bug #68547 (group octave):=0A=0AI think you're probab=
ly correct that it's not in core MATLAB.  I didn't see=0Aanything on the pa=
ge itself indicating that, but fma is not listed on=0A[https://www.mathwork=
s.com/help/matlab/referencelist.html this page] which I'm=0Aguessing is int=
ended to be a complete list of core functions.  All but ten of=0Afunctions =
linked from there seem to have URL paths starting with=0A"/help/matlab/".=
=0A=0AI don't know how Octave decides whether a function belongs in core vs=
. a=0Aseparate package.  Some points that might argue in favor of having it=
 in=0Acore:=0A* FMA is a basic low-level building block.=0A* FMA is useful =
in a large fraction of numerical computations.=0A* FMA would likely be usef=
ul in some of Octave's own m-file functions.=0A* FMA is a standard part of =
the floating point environment in many other=0Alanguages.=0A* FMA is a requ=
ired operation in IEEE 754.=0A=09* I haven't seen a claim that Octave is ai=
ming for IEEE 754 conformance, but=0Agetting closer still seems valuable.=
