摘要:

The problem of polynomial least squares fitting to a set of data leads to a system of linear equations. The solution of such a system is usually considered as something purely technical which lacks interest and is left for students to solve. We consider that the use of orthogonal polynomials here is numerically necessary and provides interesting didactic contributions.
