Dear PDL users: I will be attending the dutch Perl workshop. http://www.perlworkshop.nl/nlpw2014/talks Last year, nobody there knew that there was something like PDL.
I could at least give a small primer there on what it is, and for who. Would that be a good idea ? And if yes: does anyone have material already ? I could tell: - what exsists: matlab / octave, c/c++, numpy, R, mathematica / maxima - benefits of perl as basis (regexp, I/O, data cleaning, flexio) - great performance - known uses and library stacks based on PDL (take from http://pdl.perl.org/?page=users ) - my solution of running this in a multiple processor environment - some examples of what I use it for What do you think ?
