BSplineTensorProductBasis{N,T}(Bases::SArray)

BSpline basis on a tensor-product domain, consisting of a vector of one-dimensional bases defined on each direction of the tensor-product domain.
Where `N` describes the dimension and `T` the boundary condition.

adjoint(b::Basis)

Create a basis that consits of the derivative of basis functions in `b`.

PeriodicBSpline(basis_functions, knot_vector, interval, order, N)

Construct a `periodic` BSpline basis on `interval` with `N` points and order `k`.

mass_matrix(b::Basis)

Calculate the mass-matrix for the basis `b` with Gauss quadrature.

stiffness_matrix(b'::Basis)

Calculate the stiffnes-matrix for the basis `b` with Gauss quadrature. Caution: We directly input b' here as a basis.
