Liquid Spheroid codes

Julia and C++ code for calculations of acoustic scattering by liquid spheroids (prolate and oblate).
This code calculates the scattering far-field acoustic pressure pattern using the software executables
(pro_sphwv, obl_sphwv) for the spheroidal wave function calculation developed by Adelman, Gumerov and 
Duraiswami available at https://github.com/radelman/scattering.git (see http://arxiv.org/abs/1408.0074
for further details).

To use our code download to a folder the contents of folder Linux or Windows according to your operative
system. In Linux it can be necessary to give execution rights to the executables and the shell scripts.

In linux start a Julia shell from the command line and load the file "JUL.main.jl": this loads the core
routines in "JUL.routines.jl" and auxiliary functions in "JUL.auxiliar.jl". Some example scripts are
provided for calculation of diverse cases of oblate and prolate far-field patterns in particular cases.
These examples are based on the material exhibited in a paper submitted to Acta Acustica United with
Acustica and also in the one that will be probably at arXiv in the near future.

GSL package on Julia

The Julia codes uses the "GSL" (GNU Scientific Library) package for a marginal routine.
The basic setup implies:

Pkg.add("GSL")
Pkg.build("GSL")

but under certain circumstances one command or both fail miserably.
This is a bug related to a dependency on linux package gsl-devel. A workaround is to install previously
this package, via

$ sudo dnf install gsl-devel

and then run 

$ sudo ldconfig

to refresh the library database. And of course, update the Julia environment also.
