Read about anonymous functions.

f = @(x) 5*x^3-3*x^2+2*x-2 ; 

Any value can be evaluated using:

f(1)
f(2)

[david carlson]

i want to enter the function as [5 -3 2 -2] so matlab can record it as function of x

[KSSV]

Yes very much possible....when you enter like that, use polyval to evaluate the function at x.
