Using Ruby/GSL

Installation

See here.

Load the library

Use at the head of your scripts,

require("rb_gsl")
include GSL

or

require("gsl")

All the classes, modules, functions and constants of Ruby/GSL are defined under the top-level module GSL, or its submodules.

Naming convention

The GSL module

• Most of GSL data types, functions or constants are named as gsl_xxx or GSL_XXX. In Ruby/GSL, the prefix gsl_ is replaced by the module identifier, GSL::. For example,
  • Struct gsl_vector ---> Class GSL::Vector
  • Constant GSL_SUCCESS ---> Constant GSL::SUCCESS
  • Function gsl_sf_bessel_J0 --->
    • Submodule GSL::Sf
    • Module function GSL::Sf::bessel_J0
  • Function gsl_linalg_LU_decomp --->
    • Submodule GSL::Linalg::LU
    • Singleton method GSL::Linalg::LU.decomp
