Hi Jay,
yes. Even worse: there is another subtle difference in the inner
products of IBM APL2 and the
ISO standard.
IBM APL2 states (language reference, page 165) and also does this:
A f.g B ←→ f/¨
(⊂[⍴⍴A]A) ∘.g ⊂[1]B
The
This is a subtle difference in the definition of inner product. On vectors:
A f.g B ←→ ⊂f/A g B ⍝ APL2
A f.g B ←→ f/A g¨ B ⍝ NARS2000, Dyalog
Jay.
