Build Status


Math::Libgsl::QuasiRandom - An interface to libgsl, the Gnu Scientific Library - Quasi-Random Sequences.


use Math::Libgsl::QuasiRandom;
use Math::Libgsl::Constants;

my Math::Libgsl::QuasiRandom $q .= new: :type(SOBOL), :2dimensions;
$q.get».say for ^10;


Math::Libgsl::QuasiRandom is an interface to the Quasi-Random Sequences of libgsl, the Gnu Scientific Library.

new(Int :$type, Int :$dimensions)

The constructor allows two parameters, the quasi-random sequence generator type and the dimensions. One can find an enum listing all the generator types in the Math::Libgsl::Constants module.


This method re-inits the sequence.

get(--> List)

Returns the next item in the sequence as a List of Nums.

name(--> Str)

This method returns the name of the current quasi-random sequence.

copy(Math::Libgsl::QuasiRandom $src)

This method copies the source generator $src into the current one and returns the current object, so it can be concatenated. The generator state is also copied, so the source and destination generators deliver the same values.

clone(--> Math::Libgsl::QuasiRandom)

This method clones the current object and returns a new object. The generator state is also cloned, so the source and destination generators deliver the same values.

my $q =;
my $clone = $q.clone;

C Library Documentation

For more details on libgsl see The excellent C Library manual is available here, or here in PDF format.


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

Debian Linux

sudo apt install libgsl23 libgsl-dev libgslcblas0

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

Ubuntu 18.04

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


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

$ zef install Math::Libgsl::QuasiRandom
