inlinevirtual

Return i-th basis vector.

Parameters

[in] i is the index of the basis function.

Returns: A reference-counted pointer to the basis vector with index i.

Overloading the basis is only required if the default gradient implementation is used, which computes a finite-difference approximation.

inlinevirtual

Set \(y \leftarrow C\) where \(C\in\mathbb{R}\).

Parameters

[in] C is a scalar.

inlinevirtual

Set vector to be uniform random between [l,u].

Parameters

[in]	l	is a the lower bound.
