Today I discuss what are Chebyshev polynomials and why we need them. After Introducing Chebyshev polynomials and their properties, I will write three separate codes to generate Chebyshev polynomials in MATLAB.

Chebyshev nodes can help us interpolate functions. They are much better than linearly spaced nodes. In the video I explain why Chebyshev nodes are a better option, and provide an example to show that equally spaced nodes may lead to a wrong result.

Watch the video and tell me what you think in the comments.
