Please solve the following question using Matlab Language. I posted a picture from my lecture to show what X ,Y, and A are.

Here are some hints for the following problem:

% Be careful: xdata and ydata are nx1 column vectors.

% Set up the matrices XA = Y, use A = X\Y. (Please look at the picture for what X,Y,and A are)

% cStar - (p+1)x1. Keep this dimensioning in mind.

% err - Use the command norm(X*A-Y,2).

% flag - Should return 1 if everything is okay, -1 if an error exists.

% If size xdata and ydata are not the same -> flag = -1, cStar = empty,

err= Inf.

% If no of coefficients of polynomial (p+1) are more than no of data points, then error so same thing.

Thanks!!
