**sparse_test**,
a Python code which
tests the scipy.sparse() functions which
create sparse matrices and carry out linear algebraic functions
on them.

an Octave version and
a Python version.

test_matrix, a Python code which defines test matrices for which the condition number, determinant, eigenvalues, eigenvectors, inverse, null vectors, P*L*U factorization or linear system solution are known. Examples include the Fibonacci, Hilbert, Redheffer, Vandermonde, Wathen and Wilkinson matrices.

- sparse_test.py, calls all the tests;
- sparse_test.sh, runs all the tests.
