Hi Luis, For backward compatibility, operations default to supporting all real types, which is why you’re getting LDouble (the highest-numbered real type, but still below the complex ones). To make the various Image* operations work on native complex values, they just need telling to do so.
Could you try patching Libtmp/Image2D/image2d.pd with this at the top (cribbed from Basic/Ops/ops.pd) before the pp_addpm: my $A = [ppdefs_all]; Then add “GenericTypes => $A” to at least the pp_def of conv2d, around line 266? Please let us know if that works (you’d need to do a “make install”, or else a “make basic” then “perl -Mblib yourlocalscript.pl”). If it does, feel like PR-ing an update for all the Image* modules in Libtmp? :-) Best regards, Ed From: Luis Mochan<mailto:moc...@icf.unam.mx> Sent: 15 August 2022 17:39 To: perldl<mailto:pdl-general@lists.sourceforge.net>; perldl<mailto:pdl-de...@lists.sourceforge.net> Subject: [Pdl-general] conv2d Hello, I tried to use conv2d from PDL::Image2D to make a simple average, as in $z->conv2d(ones(3,3))/9; to take the arithmetic average a pixel with its neareast neighbors. However, what I want to average is a component of an electric field which is complex valued. It turns out that conv2d doesn't work on complex quantities and the result I obtained was of the LDouble type. Having looked further yet. Regards, Luis -- o W.
