**lagrange_interp_nd_test**,
a FORTRAN90 code which
calls lagrange_interp_nd(), which
defines and evaluates the Lagrange polynomial p(x)
which interpolates a set of data depending on a M-dimensional argument
that was evaluated on a product grid,
so that p(x(i)) = z(i).

lagrange_interp_nd, a FORTRAN90 code which evaluates the Lagrange polynomial p(x) which interpolates a set of data depending on a multidimensional argument that was evaluated on a product grid, so that p(x(i)) = z(i).

- lagrange_interp_nd_test.f90, a sample calling program.
- lagrange_interp_nd_test.sh, runs all the tests.
