Lagrange polynomial 1.0

% Polynomial Interpolation Problem: Lagrange Form% x and y are vectors with the same dimensions% Given n points: (x_k,y_k) k = 1,2,...n% this function finds a polynomial P(x) of degree less% than n such that P(x_k) = y_k% --% Remarks:% The resulting polynomial is displayed in symbolic notation% --% Example% x=[0 1 2 3 4 5 6 7];% y=[4 -6 -1 16 -2 6 12 17];% pol=show_polinterp(x,y);% --% x=[1 2 3 4 5 6 7];% y=1+x.^3-x.^6;% pol=show_polinterp(x,y);%% For evaluating pol, try% subs(pol,x), it will return vector y%--
