Math::Libgsl::Constants - An interface to libgsl, the Gnu Scientific Library - constants and exceptions.


=begin code :lang<raku>

use Math::Libgsl::Constants;
use Math::Libgsl::Exception;

=end code


This module provides the constants and the exception class used by all the other modules.


From v0.0.11 the version variable C<$gsl-version> is a C<Version> object.


To install it using zef (a module management tool):


=begin code
$ zef install Math::Libgsl::Constants
=end code

Math::Libgsl::Raw::Complex - An interface to libgsl, the Gnu Scientific Library - complex numbers.


=begin code :lang<raku>

use Math::Libgsl::Raw::Complex :ALL;

=end code


Math::Libgsl::Raw::Complex provides an interface to libgsl's implementation of complex numbers.


This package provides the low-level interface to the C library (Raw).


Math::Libgsl::Complex will not be implemented, because Raku's Complex datatype works just fine. Its Raw counterpart, Math::Libgsl::Raw::Complex, is present because it's needed by other modules that rely on the GSL implementation of complex numbers.


For more details on libgsl see L<https://www.gnu.org/software/gsl/>.
The excellent C Library manual is available here L<https://www.gnu.org/software/gsl/doc/html/index.html>, or here L<https://www.gnu.org/software/gsl/doc/latex/gsl-ref.pdf> in PDF format.


This module requires the libgsl library to be installed. Please follow the instructions below based on your platform:


=begin code
sudo apt install libgsl23 libgsl-dev libgslcblas0
=end code


That command will install libgslcblas0 as well, since it's used by the GSL.


libgsl23 and libgslcblas0 have a missing symbol on Ubuntu 18.04.
I solved the issue installing the Debian Buster version of those three libraries:


=begin code
$ zef install Math::Libgsl::Complex
=end code
