a Python version.

jordan_matrix_random, a Python code which returns a random matrix in Jordan canonical form.

snakes_matrix, a Python code which computes the transition matrix for Snakes and Ladders.

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.

wathen_matrix, a Python code which compares storage schemes (full, banded, sparse triplet, sparse) and solution strategies (A\x, linpack, conjugate gradient (CG)) for linear systems involving the Wathen matrix, which can arise when solving a problem using the finite element method (FEM).

- risk_matrix.py, calls all the tests.
- risk_matrix.sh, runs all the tests.
