Perl Data Language: Open-Source Numerical Extension for Fast Array & Matrix Manipulation

Perl Data Language (PDL) provides fast array and matrix manipulation, linear algebra, mathematical and statistical tools in an easy-to-use syntax.

What is Perl Data Language?

Perl Data Language (PDL) is an open-source extension module for the Perl programming language that provides fast array and matrix manipulation, linear algebra, mathematical and statistical tools, and graphics in an easy-to-use syntax. It was designed to facilitate data manipulation for modeling problems in fields like astronomy, biology, finance, physics, and more.

Some key features of PDL include:

• Efficient multidimensional arrays and matrices
• Broad set of mathematical, statistical, signal processing and graphics operations
• Integration with other Perl modules like Graphics::Gnuplot
• C code optimization for performance-critical algorithms
• On-the-fly compilation for frequently used operations
• Acp, GnuPlot, PGPLOT and PGPLOT graphics backends

PDL enables vectorized operations on entire arrays and matrices for order-of-magnitude speedups over scalar loops in Perl code. It can serve as a numeric workhorse for research and data analysis applications where Perl's text processing strengths can also be utilized. PDL is flexible enough for prototyping yet performant enough for production systems.
