Function Documentation

nPointStencilMethod()

template<std::size_t N, typename ContainerX, typename ContainerY = ContainerX, typename = std::enable_if_t<std::conjunction_v<std::is_default_constructible<typename ContainerX::value_type>, std::is_default_constructible<typename ContainerY::value_type>>>>

auto CppUtils::Math::details::nPointStencilMethod ( const ContainerX & x, const ContainerY & y )

constexpr

A function taking the derivative (by numerical methods) of a given function y with respect to x. Each of the functions, x and y, are represeted by containers.

Template Parameters

N	- The nPointStencilMethod to use (5, 7, or 9)
ContainerX	- A container for a default constructible type x
ContainerY	- A container for a default constructible type y

Parameters

x	- The x values to use
y	- The y values to use

Returns

A vector of equal size to the input containers with default values for the beginning and end of the vector depending on the method used

Exceptions

CppUtils::Math::InputSizeMismatch

If the sizes of the two containers don't match, we will throw an exception
