How can I have Matlab create a polynomial function from a vector of coefficients without invoking some other implemented function?

Evaluating Polynomials. After entering the polynomial into MATLAB® as a vector, use the polyval function to evaluate the polynomial at a specific value. Use polyval to evaluate p ( 2). polyval (p,2) ans = 153. Alternatively, you can evaluate a polynomial in a matrix sense using polyvalm. The polynomial expression in one variable, p ( x) = 4 x ...
