Arrgh, even PDL::Fit::Linfit depends on Slatec! This means I can't do something as simple as fitting data to a line without a FORTRAN compiler! Unless GSL has some fitting routines, but once again, I'll have to use an external dependency. Grrrr.

The package PDL::Fit::Polynomial depends on Slatec, but that's silly because Slatec has its own polynomial fitter called polyfit. This means that I can't fit my data to a line unless I use PDL::Fit::Linfit, which does linear fitting for arbitrary functions.
This is particularly frustrating since a polynomial fitter is not too hard to implement by hand. In the very least, the documentation...

Hello everybody. I wanted to announce that I've written a Perl module that allows you to send commands from Perl to a running copy of the Asymptote interpreter. The module is called Graphics::Asymptote. It also comes with another module named PDL::Graphics::Asymptote, which allows you to do your number crunching in PDL and pass the resulting vectors/matrices of data to Asymptote for final...

I want to echo what Chris just pointed out - we should differentiate between a PGPlot wrapper and a generic 2D plotting interface. My concern is that I have created a wrapper for my favorite drawing software - Asymptote - and the thought of writing a compliant interface is not very appealing. Writing a compliant interface for Asymptote would be like writing a compliant interface for gnuplot...

I just realized that I did NOT update any sort of changes file with this patch. However, upon further inspection, I couldn't find a current changes file. I only found the Changes_CVS file, which stops around April (when we switched to GIT). If somebody could point me in the right direction I'd be happy to update that and create a new patch with modifications to the CHANGES file. Sorry about...

I've modified FastRaw so that you can specify your own header file. I find this handy when I want to use the same header file for a bunch of different files. I updated the documentation, both to reflect the new capabilities and to add some usage examples. I completely rewrote the test file to use Test::More; it includes all the tests of the original fastraw.t file and a few new ones, testing...

Yes, I too thought it was odd to use Arrows to do this. But there's an invisible pen? I didn't know that... <flips through documentation>. Well, that solves my problem then. Thanks.

I have been plotting a lot of experimental data recently and I just today discovered that I can graph my data points without connecting lines by drawing with 'arrow = Blank'. For those who haven't noticed this in the documentation, drawing with a 'Blank' arrow will draw neither arrow heads nor a line, which sounds utterly pointless unless you're plotting data using markers, like I am doing. I...

Sure 'we' could. :)

Sorry about that stub. I was attempting to upload a file before finishing the statement and it thought I had said everything already!
Here's the deal. Put test.pdl and testSub.pdl in your Autoloader directory. Then call test() from the perldl prompt. Somewhere in the output, you should get something about "sub testSub...", i.e. the contents of testSub.pdl! I'll let the code speak for...
