Dyalog Forums

no idea if a windows 11 update fixed anything. First thing I did when I noticed the prob was to clear cookies, but that didn't resolve it. When I uninstalled and then reinstalled from scratch, I had wiped the machine of all traces of dyalog other than my own stuff. That didn't resolve the prob ...

sorry for delayed response...was away. help/latest enhancements - i do get the 19.0 Key features. There is no "Latest updates" option. But...somehow, now the issue has resolved. no clue how/why or when it started to work. when I uninstalled everything and reinstalled from scratch, it did not work. I ...

I uninstalled and reinstalled again (this time including the Dyalog Unicode IME. 'help'⎕na 'P hhctrl.ocx|HtmlHelpA P <0C U U4' still returns nothing help 0 'C:\\Program Files\\Dyalog\\Dyalog APL-64 19.0 Unicode\\help/dyalog.chm::/Language/Symbols/Set Union.htm' 0 0 returns an integer each time i run ...

Moved from 18 to 19.0.48959.0. The patch ws failed for me this time (most likely my fault), so I reinstalled from basically scratch sev weeks ago. Everything has been operating as usual other than when I hover on a glyph on the toolbar and click on "more". Short of reinstalling, anything I can try ...

thanks. got it. yes, 1. (⊂a)×[2]¨↓b was what i had in mind, but i kept trying to make (↓a)×[2]¨↓b because i'm an apl-1 guy at heart (and haven't coded much in the past few years which is the last time i worked thru some of the apl2 stuff). 2. "The same can be achieved using ⊢ e.g. f⍤1⊢Y because ⍤ bin ...

thanks to each of you.

Stefano, would u mind walking me through your solution?

Phil, that's more inline with what i was going for.

again, thanks guys

stuck on this abstraction of a bigger problem: a←4 2 ⍴⍳8 b←3 2⍴1 1 1 2 2 3 i want to generate a×[2]b[i;] where i loops thru the rows of b. this works: ↑, ⍉(↓a)∘.×↓b but i gotta believe there's a better way than using split and an outer product. i just haven't been able to figure it out. any help? tha ...

thanks guys. 1. in my hacked version, i failed to note that i'm playing with some large data sets and (reflexively) avoided using an outer product. 2. (⊂¨y)⌷¨x is what i was looking for. i figured squish quad or pick would be the key, but i had checked Mastering APL for the exact construct and "For n ...

Given I'm more APL than APL2: x←(1 2)(3 4 5)(6 7 8 9) y←(2 1) (3 1 2 1) (2 4) I need an idiom to return essentially each y picking out of each x, so result would be: 2 1 5 3 4 3 7 9 I know that this works: x{⍺[⍵]}¨y but: 1. i don't really understand why y indexes 'each' x. IOW, if that works, i'd thi ...
