GPhys -- a multi-purpose class to handle Gridded Physical quantities

What's new!

• Mar 7 2010 uploaded a new document: GPhys Recipes (in Japanese)

• Feb 19 2010 (gphys-1.0.0)
  • Supported interpolation, coordinate transformation, and regriding. You can also "cut" a GPhys by mouse using DCL. --- a highly frexible interpolation was implemented in C as an extension library, so you need to use extconf.rb to install.
  • and many other improvements including enhancement of GGraph graphics

• Jul 2 2009 (gphys-0.7.0)
  • supported file formats HDF-EOS5 (swath and grid) and Gtool3
  • added ganalysis - a suite of gphys applications (You need to require it explicitly by require "numru/ganalysis"
  • Support "associated coordinates" (AssocCoords), which handle scattered sampling / curvilinier coordinates / multiple axes (ToDo : general coordinate transformation and regridding)
  • GGraph enhanced
  • Vizshot removed (moved into gfdnavi_utils)
  • introduced C extension libraries
  • gpview command enhanced
  • bug fixes

Installation

• Ruby 1.8 or 1.9 (Ruby 1.6 support was given up to use DateTime)

• NArray: (perhaps 0.5.7 or later required) a multi-dimensional numeric array class for ruby.

• Misc (ver.0.0.4 or later required) Collection of miscellaneous common basic libraries for Ruby programming.

• Units (ver.1.5 or later required) Class of units of physical quantities.

• NArrayMiss (ver.1.1.2 or later required) a multi-dimensional numeric array that handles data missing.
  (at this moment, not used heavily, and GPhys is not tested well for the use with NArrayMiss)

• RubyNetCDF (ver 0.5.2 or later; perhaps 0.5.1 is also ok, but I have not checked)
  The Ruby interface of the NetCDF library.

• RubyDCL (ver 1.2.1 or later) The Ruby interface of the DCL graphic library
