**wathen_matrix_test**,
a FORTRAN77 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).
