Detailed Documentation
In this documentation, we employ orthogonal polynomials for data fitting. The process involves reading GPS sample points and performing curve fitting through computational algorithms. Notably, orthogonal polynomials represent a common data fitting methodology capable of effectively fitting various types of datasets. The implementation typically involves constructing orthogonal polynomial bases through recurrence relations, calculating polynomial coefficients using least squares approximation, and evaluating the fitted curve. Through this approach, we can achieve more accurate fitting results while gaining better insights into data relationships. Consequently, orthogonal polynomials remain a widely adopted analysis tool in scientific and engineering domains, particularly valuable for handling ill-conditioned matrices in fitting problems due to their numerical stability advantages.
