Seldom are my definitions useful as both monads and dyads(*footnote 0).
Cap documents(*1) intent as in this brief session with vectors in j:
length=: +/&.:*: : [:
to =: [: : -~
normalize =: % length : [:
c =: [: : (normalize@:to) NB. (*c)
0 c 3 4
0.6 0.8
0 length 8
|domain error: length
| 0 length 8
TeX markup also facilitates documenting j thus I've started writing
source in noweb(*3). http://www.cs.tufts.edu/~nr/noweb/
(*0) valence exception: argument defaults
(*1) [: documents and enforces
(*c) homogeneous coordinates: CSE167_03.ppt slide 55
(*3) where before I had used 0 : 0
block nouns NB. and these notes
)
Finally---a personal status report---I've made sufficient progress to
answer most of my own questions. I thank you for your patience. Dave.
