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

by T Horinouchi, S Nishizawa, S Takehiro, S Otsuka, R Mizuta, D Tsukahara, M Horikawa, T Koshiro

What's new!

Apr 15 2013 gphys-1.3.1 released.
- Solved a problem to access opendap via netcdf-4 (this is the only change)
Mar 19 2013 gphys-1.3.0 released.
- Enhanced virtual joining of GPhys(iable) objects:
  - supported joining of GPhys objects, and GPhys::IO.open is changed to use it, allowing unification of files of any kinds suppored by GPhys.
  - Suppoted unification by non-existent dimensions (e.g., to make time sequence from snapshots).
  - Supported non-monotonic division along axes, such as the latitudinal division of ISPACK with MPI (e.g., file2, file1, file0, file1, file2).
- Enhanced and improved graphics: new options in GGraph methods and gpview; improved calendar-based axes (to cover many years);
- Enhanced and improved analysis methods
- Improved dRuby support
- Lifted the protection of GPhys#grid
- Bug fixes, minor improvement & updates.

Installation with pacakges

See this page

Installation without using packages (raw installation)

The following libraries are required to use GPhys:

Ruby 1.8 or 1.9 (Ruby 1.6 support was given up to use DateTime)
NArray: (0.5.7 or later required) a multi-dimensional numeric array class for ruby.
Misc (ver.0.1.0 or later required) Collection of miscellaneous common basic libraries for Ruby programming.
Units (ver.1.7 or later required) Class of units of physical quantities.
NArrayMiss (ver.1.2.4 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 0.6.6 or later)
The Ruby interface of the NetCDF library.
RubyDCL (ver 1.6.1 or later) The Ruby interface of the DCL graphic library
Ruby-FFTW3 (ver 0.3 or later) The Ruby interface of the FFTW (ver 3) library
Ruby-GSL (ver 1.14 or later) The Ruby interface of the GNU Scientific Library

The following libraries are recommended to use GPhys:

Ruby-LAPACK (ver 1.5 or later) A Ruby interface of LAPACK - Linear Algebra PACKage

The following is used if installed and explicitly specified on runtime, but the present version (0.2.0) is not recommended unless NEEDED (i.e., to read GRIB2 files). Otherwise, please wait a new version.

rb-GRIB (ver 0.2.0 -- unstable!) A Ruby interface of ECMWF's GRIB API (support GRIB1 and GRIB2 data).

If you have installed these libraries, to install GPhys is quite easy:

% tar xvzf gphys-version.tar.gz
% cd gphys-version
% ruby extconf.rb
% make
% sudo make install
% sudo ruby install.rb
