Orthogonal Polynomials Approximation 数值分析，计算正交基多项式的系数 -Given a function f and a set of m >0 distinct points . You are supposed to write a function to approximate f by an orthogonal polynomial using the exact function values at the given m poin

Polynomial approximations (square method) In mathematics, approximation theory is concerned with how functions can best be approximated with simpler functions, and with quantitatively characterizing the errors introduced thereby. Note that what
