coeffs()

AffineCubicOperator.coeffs(parameter)

Evaluate the coefficient functions for each term of the affine expansion for a given parameter vector.

This method represents the vector-valued function \(\boldsymbol{\theta}_{\ell} : \RR^{p} \to \RR^{A_{\ell}}\) given by \(\boldsymbol{\theta}_{\ell}(\bfmu) = [~ \theta_{\ell}^{(0)}~~\cdots~~\theta_{\ell}^{(A_{\ell}-1)}~]\trp.\)

Parameters:

parameter(p,) ndarray

Parameter vector to evaluate.

Returns:

coefficients(nterms,) ndarray

Coefficients of the affine expansion at the given parameter.
