Math::...eMatrix(3pm)

✨ NAME ✨

Math::GSL::SparseMatrix — Sparse Matrices 🦋 (and yes bestie, the man header literally renders it as Math::...eMatrix(3pm) because those long Perl module names cannot fit in the top line, it's giving cropped for the algorithm 💅)

🌸 SYNOPSIS 🌸

use Math::GSL::SparseMatrix qw/:all/;
use Math::GSL::Matrix qw/gsl_matrix_alloc/;
my $sparse = gsl_spmatrix_alloc(100,100);
my $status = gsl_spmatrix_set($sparse,50,50,42.42);
my $value  = gsl_spmatrix_get($sparse,50,50);

# multiply every element by 5
$status = gsl_spmatrix_scale($sparse, 5);

# get the number of non-zero elements
my $nnz = gsl_spmatrix_nnz($sparse);

# fine min and max values, other than zero elements
($status, $min, $max) = gsl_spmatrix_minmax($sparse);

# set all elements to zero
$status = gsl_spmatrix_set_zero($sparse);

my $dense  = gsl_matrix_alloc(100,100);
# convert a sparse matrix to a dense matrix
$status = gsl_spmatrix_sp2d($dense, $sparse);

# convert a dense matrix to a sparse matrix
$status = gsl_spmatrix_d2sp($sparse, $dense);

okay so literally just skim that and you already know what this module does 😭 it's sparse matrices, it's the whole vibe, no cap.
