Syntax y = polyval(p,x) [y,delta] = polyval(p,x,S) y = polyval(p,x,[],mu) [y,delta] = polyval(p,x,S,mu)Description y = polyval(p,x) evaluates the polynomial p at each point in x. The argument p is a vector of length n+1 whose elements are the coefficients (in ...
This MATLAB function returns the coefficients for a polynomial p(x) of degree n that is a best fit (in a least-squares sense) for the data in y.
