Hi all


I’ve moved my SciPDL distribution (easy MacOS kitchen sink install) to a new location:



















PDLPorters/SciPDL: This is a repository for creating SciPDL distributions (easy install of PDL on MacOS)

github.com














This means I can do ‘releases’ without mucking up the main GitHub repo (sorry Ed!)


I have even updated the pdl.perl.org web pages to point there, (first change in 2 years!)


Will add some more recent versions. I have 2.084 sitting on disk (Arm and Intel) so I will just re-check and put that up in the next few days, and then look at v2.087 which is hopefully straight forward…


I hope this is a good approach for the future.


best


Karl

[Pdl-general] Plotting flat xyz data as an image.

2024-04-17 Thread Jovan Trujillo 
Hi all,

I've been wracking my brain all morning trying to figure this out, but how
could I convert a set of 3 1D piddles containing xyz data into a matrix for
plotting as an image using PDL::Graphics::Gnuplot? Say for example:

use PDL;
use PDL::Graphics::Gnuplot qw/image gplot/;

my $x = flat(xvals(10,10)); # This is basically how x-coordinates are
output from my machine.
my $y = flat(yvals(10,10)); # Same format as x-coordinates
my $z = sequence(100)*rand(1); # Some dummy data for this example.

my $image; # How do I map $x,$y,$z into this 10x10 $image piddle?
image($image);

That's my basic problem. How do I map $x,$y,$z data into an $image matrix?

Thank you,
Jovan

Hi Karl,

This seems like a really good approach!

I'm wondering whether to piggyback off the same repo to host the upcoming 
Homebrew recipe for PDL, or make a new one? Probably the latter to minimise 
conflicts.

Best regards,
Ed
