say I have a vector such as [1,2,3,4,5] which represents the function x^4 + 2x^3 + 3x^2 + 4x + 5. How could matlab directly interpret a vector as a polynomial function, and plot it? Thanks.

From MATLAB documentation:
The polynomial p(x) = 3x^2 + 2x + 1 is evaluated at x = 5, 7, and 9 with
p = [3 2 1];
polyval(p,[5 7 9])
which results in ans =
86 162 262
