Tīmeklis上面這樣的多項式就稱為 拉格朗日（插值）多項式 （Lagrange polynomial）。. 數學 上來說，拉格朗日插值法可以給出一個恰好穿過二維 平面 上若干個已知點的多項式函 … A better form of the interpolation polynomial for practical (or computational) purposes is the barycentric form of the Lagrange interpolation (see below) or Newton polynomials. Lagrange and other interpolation at equally spaced points, as in the example above, yield a polynomial oscillating above and … Skatīt vairāk In numerical analysis, the Lagrange interpolating polynomial is the unique polynomial of lowest degree that interpolates a given set of data. Given a data set of coordinate pairs Although named … Skatīt vairāk Each Lagrange basis polynomial $${\textstyle \ell _{j}(x)}$$ can be rewritten as the product of three parts, a function By factoring Skatīt vairāk The Lagrange form of the interpolation polynomial shows the linear character of polynomial interpolation and the uniqueness of the interpolation polynomial. Therefore, it is preferred in proofs and theoretical arguments. Uniqueness can also be seen … Skatīt vairāk The dth derivative of a Lagrange interpolating polynomial can be written in terms of the derivatives of the basis polynomials, Skatīt vairāk Given a set of $${\textstyle k+1}$$ nodes $${\displaystyle \{x_{0},x_{1},\ldots ,x_{k}\}}$$, which must all be distinct, $${\displaystyle x_{j}\neq x_{m}}$$ for indices $${\displaystyle j\neq m}$$, the Lagrange basis for polynomials of degree Notice that the … Skatīt vairāk We wish to interpolate $${\displaystyle f(x)=x^{2}}$$ over the domain $${\displaystyle 1\leq x\leq 3}$$ at the three nodes Skatīt vairāk When interpolating a given function f by a polynomial of degree k at the nodes $${\displaystyle x_{0},...,x_{k}}$$ we get the remainder $${\displaystyle R(x)=f(x)-L(x)}$$ which can be expressed as where Skatīt vairāk
TīmeklisI'm almost a decade late to the party, but I found this searching for a simple implementation of Lagrange interpolation. @smichr's answer is great, but the … Tīmeklis2015. gada 8. jūl. · Lagrange interpolation is a way of crafting a function from a set of data pairs. The resulting function passes through all the data points you give it (like a Catmull-Rom spline does), so can be used to find a function to interpolate between data sets. You can’t give two value pairs that have the same x value, but the data points …
