evalPol {MonoPoly} | R Documentation |
Function to evaluate polynomials in a numerical robust way using the Horner scheme
evalPol(x, beta)
x |
numerical values at which to evaluate polynomials, can be provided in a vector, matrix, array or data frame |
beta |
numerical vector containing the coefficient of the polynomial |
The result of evaluating the polynomial at the values in x
,
returned in the same dimension as x
has.
