How to calculate a polynomial with specified point in MatLab?

[Ans]

polyval

[description]

Evaluate polynomial

<Y> = polyval(<P>,<X>)

It will return the value of a polynomial P evaluated at X.

<P> is a vector of length N+1 whose elements are the coefficients of the

polynomial in descending powers:

Y = P(1)*X^N + P(2)*X^(N-1) + ... + P(N)*X + P(N+1)

P is vector type.

<X> is a given value

double or single or int type.
