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

What's new!

• Aug 15 2011 gphys-1.1.1 released.
  • Added the LICENCE file (BSD 2-cluase).
  • GGraph: added regression line drawing (method regression_line). Added new options to the method vector.
  • Bug fixes / enhancement for NuSDaS IO, NetCDF, and GRIB IO.
  • Other minor updates, improvement, and bug fixes.

• Feb 19 2010 gphys-1.1.0 released.
  • Added/enhanced analyses library: ganalysis/eof.rb, ganalysis/met.rb, ganalysis/covariance.rb, ganalysis/planet.rb
  • Enhanced the graphic library ggraph.rb: scatter diagrams
  • GRIB IO was speeded up by using extension library etc
  • Support calendars
  • enhanced gpview and gpvect commands
  • Extension for DCL 5.3.4
  • Support Ruby 1.9.2
  • Bugfixes

• 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

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

• Ruby-FFTW3 (ver 0.2 or later) The Ruby interface of the FFTW (ver 3) library
