vandermonde_interp_1d, a MATLAB library which finds a polynomial interpolant to data y(x) of a 1D argument, by setting up and solving a linear system for the polynomial coefficients, involving the vandermonde matrix.

- vandermonde_interp_1d_test.m, calls all the tests;
- vandermonde_interp_1d_test.sh, runs all the tests;
- vandermonde_interp_1d_test.txt, the output file.

- vandermonde_interp_1d_test01.m, computes the interpolant for a given problem.
- vandermonde_coef_1d_test.m
- vandermonde_matrix_1d_test.m
