Extract coefficients from a "minimaxApprox" object
Description
Extracts the numerator and denominator vectors from a "minimaxApprox"
object. For objects with both Chebyshev and monomial coefficients, it will
extract both.
Usage
## S3 method for class 'minimaxApprox'
coef(object, ...)
Arguments

An object inheriting from class |

Value
Coefficients extracted from the "minimaxApprox" object. A
list containing:
a |
The polynomial coefficients or the rational numerator coefficients. |
b |
The rational denominator coefficients. Missing for polynomial approximation. |
aMono |
The polynomial coefficients or the rational numerator coefficients for the monomial basis when the approximation was done using Chebyshev polynomials. Missing if only the monomial basis was used. |
bMono |
The rational denominator coefficients for the monomial basis when the approximation was done using Chebyshev polynomials. Missing if either only the monomial basis was used or for polynomial approximation. |
