What would a good script m-file that calculates A polynomial of degree n?

I want to be able to write this file where I can input a x value and a c value for the polynomial. Ex. p(x)= c1 = c2*x + c3*x^2+...+cn+1 x^(n). I want find the value of p(x)

I think it has something to do with using vectors and the input, but I am not really sure.

Apparently my polyval suggestion wasn’t the Answer, so I deleted my reference to it.
