软件应用简介

newton2poly generates the polynomial formula given newton interpolation coefficients and x-coordinate interpolation nodes.

newton2poly generates the polynomial formula given newton interpolation coefficients and x-coordinate interpolation nodes as:

p(x) = c(1) + c(2)*(x-nodes(1)) + c(3)*(x-nodes(1))*(x-nodes(2))…

INPUT:

c -> column vector containing newton polynomial coeffcients from the

function interpN(x, y)

nodes -> column vector containing x-coordinate interpolation points

OUTPUT:

p -> polynomial formula of newton interpolation
