**barycentric_interp_1d_test**,
a C code which
calls barycentric_interp_1d(), which
defines and evaluates the Lagrange polynomial p(x)
which interpolates a set of data, so that p(x(i)) = y(i).
Because a barycentric formulation is used, polynomials of very high
degree can safely be used.

barycentric_interp_1d, a C code which defines and evaluates the barycentric Lagrange polynomial p(x) which interpolates a set of data, so that p(x(i)) = y(i). The barycentric approach means that very high degree polynomials can safely be used.

- barycentric_interp_1d_test.c, a sample calling program.
- barycentric_interp_1d_test.sh, runs all the tests.
