If there are only monadic functions, you can use juxtaposition to denote function composition: f=: f0 f1 f2 ... or, as in conventional mathematical notation, use the simple ∘ (jot): f=: f0 ∘ f1 ∘ f2 ∘ ... But when dyadic functions are involved, functions can be composed in different ways and you need the composition operators @ & &. fork etc. On Wed, Feb 26, 2014 at 7:05 AM, Jon Hough <jgho...@outlook.com> wrote: > Thanks for replying, everyone.Sorry the formatting was all garbled.
