chebyshev, a MATLAB code which computes the Chebyshev interpolant/approximant to a given function over an interval.

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

- chebyshev_test01.m, tests CHEBYSHEV_COEFFICIENTS and CHEBYSHEV_INTERPOLANT on several functions.
- f1.m, f(x) = cos ( 2.0 * pi * x ) .* sin ( 3.0 * pi * x );
- f2.m, f(x) = exp(x);
- f3.m, f(x) = ( x - 3 ) .* ( x - 1 ) .* ( x - 1 ) .* ( x + 2 );
