The thought occurred to me that we are approaching the 20-year anniversary of PDL this coming October 23rd!
It is amazing to me that it is now this old, doesn’t seem like 20 years has gone by. Makes me feel really old. Here is the original announcement for the nostalgic: https://groups.google.com/forum/#!searchin/comp.lang.perl.misc/glazebrook$20pdl/comp.lang.perl.misc/MJ8TL5pDaUk/LKWfyhHNCooJ Do we want to mark this in anyway? Maybe release a ‘final' version of PDL 2? (which should be v.2.71828182845905 following Knuth...) Karl p.s. First stupid code was written in Feb of 1996 - this is described in the PDL book. ———— Subject: ANNOUNCE: perlDL v1.00 - the 'perl Data Language’ 10/23/96 `perlDL' ("perl Data Language") gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N- dimensional data arrays which are the bread and butter of scientific computing. The idea is to turn perl in to a, free, array-oriented, numerical language in the same sense as commerical packages like IDL and MatLab. One can write simple perl expressions to manipulate entire numerical arrays all at once. For example with `perlDL' the perl variable `$a' can hold a 1024x1024 floating point image, it only takes 4Mb of memory to store it and expressions like `$a=sqrt($a)+2' would manipulate the whole image in a few seconds. A simple interactive shell ("`perldl'") is provided for command line use together with a module ("`PDL'") for use in perl scripts. v1.00 is the first official alpha release. It provides the fundumental numerical processing facilities and a limited set of standard functions. Graphics are supported via the perl PGPLOT module and image display via the external programs saoimage/ximtool. The goal is to allow perlDL to interact with a variety of external graphics systems. I/O is currently supported via the FITS standard, though given the simple design it ought to be possible to create perl code to read many common formats. There are of course many things missing from this first release but it is hoped that perlDL will grow through efforts of interested users. It has a modular design to encourage this.
