polyval¶

polyval calculates the y coordinates of a polynomial of degree n evaluated at x.

Return Value

y is a vector with y coordinates.

Parameters

p

p is a vector of length n+1 whose elements are the coefficients in descending powers of the polynomial to be evaluated:

$P(x) = p_1x^n + p_2x^{n-1}+ \dotsb + p_{n}x + p_{n+1}$

Example

polyval([2,3], 0:5)
 3.0000     5.0000     7.0000     9.0000    11.0000    13.0000
