Source Code:

• lagrange_basis_display_test.m, calls all the tests.
• lagrange_basis_display_test.sh, runs all the tests.
• lagrange_basis_display_test.txt, the output file.

Plots made by the test include:

• lagrange_10_chebyshev.png, the Lagrange basis functions of degree 10, for the Chebyshev points on [-1,+1].
• lagrange_10_evem.png, the Lagrange basis functions of degree 10, for evenly-spaced points on [0,+1].
• standard_10.png, the standard monomial basis functions up to degree 10, for evenly-spaced points on [0,+1].
