View on Github →chore: swap argument order in cfc
and cfcₙ
(#11468)
This changes the argument order for cfc
and cfcₙ
from cfc (a : A) (f : R → R)
to cfc (f : R → R) (a : A)
. This has a few advantages:
- It's closer to the usual reading (
cfc f a
vs.f(a)
on paper). - argument order looks better for
cfc_comp
(cfc (g ∘ f) a = cfc g (cfc f a)
instead ofcfc a (g ∘ f) = cfc (cfc f a) g
). - it will be much easier to speak of operator convexity and monotonicity if we can just write
cfc f
.
