double sumWith(geom::Point2D const &point, Vector const &coefficients, Workspace &workspace) const
Evaluate a basis expansion with the given coefficients (external workspace version).

Evaluate a basis expansion with the given coefficients.
... Function
A Function2d object that uses this basis.
Definition: Basis2d.h:41
std::size_t size() const
Return the number of basis functions.
... Workspace
The type returned by makeWorkspace().
Definition: Basis2d.h:47
... Scaled
The type returned by scale().
Definition: Basis2d.h:44
void fill(geom::Point2D const &point, Vector &&basis) const
Evaluate the basis at a given point.
Workspace makeWorkspace() const
Allocate workspace that can be passed to sumWith() and fill() to avoid repeated memory allocations.
std::size_t getOrder() const
Return the maximum order of the basis.
Scaled scaled(Scaling2d const &first) const
Return a scaled basis that delegates to a copy of this.
void fill(geom::Point2D const &point, Vector &&basis, Workspace &workspace) const
Evaluate the basis at a given point (external workspace version).
