Hi Rowan,
⍨ operator: you are using it to avoid parentheses?
Beside of restructuring code, avoiding duplicate code-fragment and
parentheses, ⍨ has no "functional" impact?

Hi Kacper,
many, many thanks for your insights!

(+\(⍴,⍵)⍴⍺↑1) - cool, generating the right binary vector and scan it...
I get more and more the impression, binary vectors - in conjunction with
f.e. scan and reduce are basis of

I've been mulling over methods of bringing linear algebra methods into
gnu-apl, specifically eigenvalues & eigenvectors (leaving open the
possibility for more).
The canonical methods for this are from LAPACK (which was formerly a
compilation dependency).
Specifically:
dgeev
dsyev
zheev
Hi Blake,
thanks, fixed in SVN 1260.
There was an error in the comparison of function names which made
⎕FX think that the function was pendant. A return value of 1 from
⎕FX
(as below) indicates an error.
Best Regards,
Jürgen
Works perfectly. Thanks a lot!!

correct. ⍨ is the commute operator when used dyadically. I generally use it
to preserve right to left reading vs nested parentheses or variable
assignment.
