ruby-gsl

ruby-gsl is a wrapper of the GNU Scientific Library for the Ruby programming language.

The GNU Scientific Library is a collection of routines for numerical computing.

Ruby is an interpreted scripting language for quick and easy object-oriented programming.

Have a look at the samples, to see what you can do with ruby-gsl!

Things implemented in ver. 0.2.0:

some error handling (ch. 3 in the GSL documentation)
basic mathematical functions (ch. 4)
complex numbers (ch. 5)
functions for polynomial evaluation/roots (ch. 6)
most "special functions" (ch. 7)
vectors and matrices (ch. 8)
permutations (ch. 9)
combinations (ch. 10)
BLAS support (ch. 12)
linear algebra (ch. 13)
eigensystems (ch. 14)
some support for numerical integration (ch. 16)
random number generation (ch. 17)
quasi-random sequences (ch. 18)
most random number distributions (ch. 19)
most statistical functions (ch. 20)
histograms (ch. 21)
Monte Carlo integration (ch. 23)
Simualted Annealing (currently broken) (ch. 24)
interpolation (ch. 26)
numerical differentiation (ch. 27)
Chebyshev approximation (ch. 28)
series acceleration (ch. 29)
Discrete Hankel Transforms (ch. 30)
1-dimensional root-finding (bracketing-based) (ch. 31)
1-dimensional minimization (ch. 32)
some functions for least-squares fitting (ch. 35)
physical constants (ch. 37)

We tried to keep the names/arguments/etc. as close to the original GSL functions so that reading the GSL documentation should suffice to use ruby-gsl. However in some places it might be more appropriate to convert some functions to a more rubyesque way.

As of version 0.1.2 we included source from Yoshiki Tsunesada's Ruby/GSL. This way we will have some nice and complete GSL wrapper some day...

If you have any questions or spot errors please feel free to contact me.
