Random Sparse Matrix Generator in Python

In brief

This Python package implements the function random_sparse_matrix that generates random sparse matrices.

The sparse matrices have named rows and columns -- see the package "SSparseMatrix", [AAp1].

Functions from the package "RandomDataGenerators", [AAp2], are used to obtain row- and column names and entry values.

Examples

Here is random sparse matrix (SSparseMatrix object) with 6 rows and 4 columns:

import random
from RandomSparseMatrix import *

random.seed(87)
rmat = random_sparse_matrix(6, 4,
                            column_names_generator=random_pet_name,
                            row_names_generator=random_word,
                            min_number_of_values=6,
                            max_number_of_values=None)
rmat.print_matrix(n_digits=20)
