MATLAB: I have an polynomial f(x) = 4x^5 + 5x^4 + 2x^3 +2x^2 +3x. And x ranges from {0 to 63}. How to code this so I can display answer corresponding to every value of x.

for loop

Could you help me?

p=[4 5 2 2 3 0];
x0=1;
polyval(p,x0);

evaluates your polynomial at x0=1.

Best wishes

Torsten.

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

I don’t believe there is a solution in the sense that:

Eqn1 = 1/(24*(x^4/24 + x^3/24 + x^2/24 + x/24 + 1/24)) == 0;

because this is the essential equivalent of a much simpler equation:

Eqn = 1/(x + 1) == 0;

Consider:

L = limit(Eqn, x, Inf)
L = 0

and the only solution is :

x -> Inf
