**lagrange_nd_test**,
a C++ code which
calls lagrange_nd(), which
is given a set of ND points X(*) in D-dimensional space, and constructs
a family of ND Lagrange polynomials P(*)(X), associating polynomial P(i)
with point X(i), such that, for 1 <= i <= ND,

P(i)(X(i)) = 1but, if i =/= j

P(i)(X(j)) = 0

lagrange_nd, a C++ code which implements several multivariate Lagrange interpolation schemes developed by Tomas Sauer.

- lagrange_nd_test.cpp, a sample calling program.
- lagrange_nd_test.sh, runs all the tests.
- lagrange_nd_test.txt, the output file.
