Polynomial expansion: Separating polynomial coefficients and x's
I want to automatically calculate expansions of polynomials where there are variables (x1,x2,...) as well as coefficients (c1,c2, ...). My goal is to calculate p(1)*(c1*x1+c2*x2+...)^n+ ... + p(n)*(c1*x1+c2*x2+...)^n .
As you can notice the…

polynomial fit trough points in matlab
I'm trying to find best polynomial fit to set of input points.
this is my code so far:
x=(1:length(meanValues));
y=meanValues(:);
A=fliplr(vander(x));
v=A \ y;
P(1: length(x))=0;
for i=1: length(x)
for j=1:…

Could this task be solved using more functional approach?
I'm writing simple polynomial-related library for my own needs. As for now, I'm working with just the polynomials in polynomial basis over GF(2), so they are represented simply as
case class Polynomial(coeffs: BitSet)
So I can just write something…
