LinearBasisFactory

class LinearBasisFactory(*args)

Linear basis factory.

The linear basis is the collection of functions \psi_k: \mathbb{R}^d \mapsto \mathbb{R} for 0 \leq k \leq d defined:

\psi_0(x_1, \dots, x_d) & = 1 \\ \psi_k(x_1, \dots, x_d) & = x_k \mbox{for } 1 \leq k \leq d

Parameters:
dimensioninteger

Input dimension d of the basis.
