--- name: "Math::GSL" section: "3pm" platform: "linux" package: "libmath-gsl-perl" version: "0.45-2+b1" release: "Debian 13 (Trixie)" platforms: ["linux"] url: "https://new.carta.tech/Math::GSL" --- # Math::GSL(3pm) Perl interface to the GNU Scientific Library (GSL) ## NAME Math::GSL - Perl interface to the GNU Scientific Library (GSL) ## VERSION Version 0.45 ## SYNOPSIS ``` use Math::GSL::Matrix; my $matrix = Math::GSL::Matrix->new(5,5); # 5x5 zero matrix # note that columns and rows are zero-based $matrix->set_col(0, [1..5]) # set *first* column to 1,2,3,4,5 ->set_row(2, [5..9]); # set *third* column to 5,6,7,8,9 my @matrix = $matrix->as_list; # matrix as Perl list my $gsl_matrix = $matrix->raw; # underlying GSL object use Math::GSL::RNG; my $rng = Math::GSL::RNG->new; my @random_numbers = $rng->get(1000); use Math::GSL::Deriv qw/:all/; my $function = sub { my $x=shift; sin($x**2) }; my ($status,$val,$err) = gsl_deriv_central($function, 5, 0.01 ); use Math::GSL qw/gsl_version/; # get a version object for the version of the underlying GSL library, # which will stringify to a version number my $gsl_version = gsl_version(); ``` Each GSL subsystem has its own module. For example, the random number generator subsystem is Math::GSL::RNG. Many subsystems have a more Perlish and object-oriented frontend which can be used, as the above example shows. The raw GSL object is useful for using the low-level GSL functions, which in the case of the Matrix subsystem, would be of the form gsl\_matrix\_\* . Each module has further documentation about the low-level C functions as well as using the more intuitive (but slightly slower) object-oriented interface. ## SUBSYSTEMS Math::GSL::BLAS - Linear Algebra Functions Math::GSL::BSpline - BSplines Math::GSL::CBLAS - Linear Algebra Functions Math::GSL::CDF - Cumulative Distribution Functions Math::GSL::Chebyshev - Chebyshev Polynomials Math::GSL::Combination - Combinatoric Functions Math::GSL::Complex - Complex Numbers Math::GSL::Const - Various Constants Math::GSL::DHT - Discrete Hankel Transforms Math::GSL::Deriv - Numerical Derivative Math::GSL::Eigen - Eigenvalues and Eigenvectors Math::GSL::Errno - Error Handling Math::GSL::FFT - Fast Fourier Transform Math::GSL::Fit - Curve Fitting Math::GSL::Heapsort - Sorting Heaps Math::GSL::Histogram - Histograms Math::GSL::Histogram2D - 2D Histograms Math::GSL::Integration - Numerical Integration Math::GSL::Interp - Interpolation Math::GSL::Linalg - Linear Algebra Math::GSL::Machine - Machine Specific Information Math::GSL::Matrix - NxM Matrices Math::GSL::Min - Minimization Math::GSL::Monte - Monte Carlo Integrations Math::GSL::Multifit - Multivariable Fitting Math::GSL::Multimin - Multivariable Minimization Math::GSL::Multiroots - Muiltvariable Root Finding Math::GSL::NTuple - N Tuples Math::GSL::ODEIV - Ordinary Differential Equation Solvers (Initial Value Problems) Math::GSL::Permutation - Permutations Math::GSL::Poly - Polynmials Math::GSL::PowInt - Integer Power Functions Math::GSL::QRNG - Quasi-Random Number Generators Math::GSL::RNG - Random Number Generators Math::GSL::Randist - Random Number Distributions Math::GSL::Roots - Root Finding Algorithms Math::GSL::Rstat - Running Statistics Math::GSL::SF - Special Functions Math::GSL::Siman - Simulated Annealing Math::GSL::Sort - Sorting Math::GSL::SparseMatrix - Sparse Matrices Math::GSL::Spline - Splines Math::GSL::Statistics - Statistics Functions Math::GSL::Sum - Summation Math::GSL::Sys - System utility functions Math::GSL::Vector - N-dimensional Vectors Math::GSL::Wavelet - Basic Wavelets Math::GSL::Wavelet2D - 2D Wavelets ## AUTHORS Jonathan "Duke" Leto, `""` and Thierry Moisan `""` ## BUGS This software is still in active development, we appreciate your detailed bug reports and documentation patches. Please report any bugs or feature requests to the authors directly. ## COMPILING ISSUES Some operating system configurations will make the compilation of Math::GSL fail. One common problem that happens on RedHat Linux (RHEL) and CentOS looks like this: ``` Error: Can't load '/usr/src/misc/perl-package/Math-GSL-0.20/blib/arch/auto/Math/GSL/Errno/Errno.so' for module Math::GSL::Errno: /usr/src/misc/perl-package/Math-GSL-0.20/blib/arch/auto/Math/GSL/Errno/Errno.so: cannot restore segment prot after reloc: Permission denied at /usr/lib/perl5/5.10.0/i386-linux-thread-multi/DynaLoader.pm line 203. # at blib/lib/Math/GSL/Errno.pm line 10 ``` This is due to the SE Linux setting being set to "enforcing". To Temporarily disable enforcement on a running system: ``` /usr/sbin/setenforce 0 ``` To permanently disable enforcement during a system startup change "enforcing" to "disabled" in ''/etc/selinux/config'' and reboot. ## SUPPORT You can find documentation for this module with the perldoc command. ``` perldoc Math::GSL ``` or online at \ - • AnnoCPAN: Annotated CPAN documentation \ - • CPAN Ratings \ - • Search CPAN \ ## DEVELOPMENT If you would like the help develop Math::GSL, visit us on Github \ and fork, send Pull Requests and/or create issues.
