Lagrange's Polynomial Interpolation based on weighted factors or Lagrange polynomials with sum = 1.
Example data:
x = [1 4 6 5]; % x vector
y = log(x); % y = f(x) vector
xp = 2 or xp = [2 3]; % x point(s) (scalar or vector) query
Use:
yp = Lagrangeinterp(x,y,xp)
to calculate
yp = f(x point) point(s) (scalar or vector)
[~,L] = Lagrangeinterp(x,y,xp)
to output the Lagrange polynomial cell array
