A basis interface for 1-d series expansions.
Definition: Basis1d.h:36
double sumWith(double x, Vector const &coefficients) const
Evaluate a basis expansion with the given coefficients.
std::size_t getOrder() const
Return the order of the basis.
... Function
A Function1d object that uses this basis.
Definition: Basis1d.h:40
Scaled scaled(Scaling1d const &scaling) const
Return a scaled basis that delegates to a copy of this.
std::size_t size() const
Return the number of elements in the basis.
... Scaled
The type returned by scale().
Definition: Basis1d.h:43
void fill(double x, Vector &&basis) const
Evaluate the basis at a given point.
A 1-d affine transform that can be used to map one interval to another.
