QuadraticBasisFactory¶

class QuadraticBasisFactory(*args)¶

Quadratic basis factory.

The quadratic basis is composed of the quadratic terms of the canonical basis:

$\{ \psi_k(x) \} = \{ 1, x_1, \hdots, x_n, x_i x_j \forall i,j \in [1,n] \}$

Parameters:

dimensionint: Input dimension of the basis.

Methods

`build`()	Build the basis.
`getClassName`()	Accessor to the object's name.
`getName`()	Accessor to the object's name.
`hasName`()	Test if the object is named.
`setName`(name)	Accessor to the object's name.

Examples

>>> import openturns as ot
>>> basis = ot.QuadraticBasisFactory(2).build()
>>> f = ot.AggregatedFunction(basis)
>>> x = [2, 3]
>>> print(f(x))
[1,2,3,4,6,9]
