  1. Plotting in Perl Yu-Tzu Chou 499440419Earth Science 103

  2. Geophysics Needing to do: • Graphing • Plotting • Contours Use: • Radan • Matlab

  3. Matlabvs Perl • General purpose programming • PDL is an extension of Perl • Most syntax differences between Matlab & PDL are because of the Perl foundation

  4. Matlab Perl • Vectors • Matrices • Arrays • Has arrays • Piddle- consists of a series of numbers organized as an N-dimensional data. Terminology

  5. Command Window & IDE Perl: • Does not have IDE • It comes with an interactive shell(use a Perl IDE to develop PDL programs)

  6. Writing PDL programs • One popular IDE for Perl is called Padre. It is cross platform and easy to use • A stand-alone PDL program one must start the program with use PDL • This command imports the PDL module into Perl

  7. Codes

  8. Plotting and Graphics • In Perl it relies on the third-party libraries for the 2D or 3D graphing • In Matlab it takes up quite some space for a data and takes time to load

  9. Matlab

  10. Perl
