**chebyshev_interp_1d_test**,
a MATLAB code which
calls chebyshev_interp_1d(), which
determines the combination of Chebyshev polynomials which
interpolates a set of data, so that p(x(i)) = y(i).

chebyshev_interp_1d, a MATLAB code which determines the combination of Chebyshev polynomials that interpolates a set of data, so that p(x(i)) = y(i).

- chebyshev_interp_1d_test.m, calls all the tests;
- chebyshev_interp_1d_test.sh, runs all the tests;
- chebyshev_interp_1d_test.txt, the output file.

- chebyshev_interp_1d_test01.m, plots a piecewise linear interpolant to the original data, and the Chebyshev interpolant.

The program plots a piecewise linear interpolant to the original data, and the Chebyshev interpolant.
