polyval - polynomial evaluation
Calling Sequence
-
y = polyval(C,x)
Parameters
-
C
: Polynomial coefficients (vector)
-
x
: Scalar, vector matrix with values, where the polynial should
be evaluated
-
y
: Result of polynomial evaluation
Description
-
POLYVAL behaves like the matlab function polyval. But it is
realized with standard SciLab functions "poly" and "horner". C
(length=N+1) builds a polynomial with the form
-
Y=C(1)*x^N + c(2)*x^(N-1) + ... + C(N)*x + C(N+1)
Examples
a=[3,2,-4,1.5];
x=-10:1:10;
y=polyval(a,x)
