Quoting horv77 (firstname.lastname@example.org):
I need a multivariable non-linear equation solver in Ruby that approximate
the optimal values for the variables that give the least differences. The
input is the function and the variables and the output is the values of
the fitted variables.
Is anyone familiar with any solution that must not involve installing
external codes from different language implementations like GSL written in
C or Scipy from Python etc.?
Sciruby maintains a list of existing gems, maybe you can find what
you need there:
I have to say, anyway, that an interpreted language (like Ruby, but
also Python) is not suitable for heavy maths. Even if a package has
ever been developed for Ruby that does what you ask, chances are its
calculating core has been written in a low-level language like C,
unless the authors have decided to pay a hefty price in performance.
