polyval
Evaluates a given polynomial using specified coefficients and datapoints.
Syntax
polyval(indep_vec, coeffs)
Argument
- indep_vec
- The independent vector.
- coeffs
- The coefficients of the polynomial.

Given c1, a curve is created which contains the values of 1 + x2 from 0 to 10. |
Comments
The coefficients are ordered from the 0th to nth order. Therefore:
1 + 4x2
is written as:
{1,0,4}
The zero in the second vector of coefficients is necessary to indicate that no linear term appears in the equation. The first vector of independent values is used to calculate the dependent (output) vector.
