class FunctionAXPY

This class represents a linear combination of functions. It is mostly used as an intermediate class for operations such as u = 3*u0 + 4*u1; where the rhs generates an FunctionAXPY.

enum Direction

Enum to decide what way AXPY is constructed

FunctionAXPY(const Function& func, double scalar)

Constructor

Constructor

FunctionAXPY(std::vector<std::pair<double, const Function*>> pairs)

Constructor

FunctionAXPY(const FunctionAXPY& axpy)

Copy constructor

FunctionAXPY operator+(const Function& func) const

Addition operator

FunctionAXPY operator+(const FunctionAXPY& axpy) const

Addition operator

FunctionAXPY operator-(const Function& func) const

Subtraction operator
