Some Notes

The example is the Luminosity distribution of a Galaxy, of a star and near the end of the talk (starting at about 40:30) he talks about visualizing blood glucose readings.

PDL provides 2 main things to Perl:

Speed and Compact data storage.

Because loops are running in C and data is stored in C variables.

If you are writing a for loop it is a sign that you are doing something wrong and it is time to send an e-mail to the PDL mailing list.

PDL has support for bad numbers.
