Math Vector

Overview

This library provides low weight vector objects that support vector addition & scalar multiplication. There are implementations for two space vectors, three space vectors, & a template length vector. All of these classes & functions are located in the namespace MathVector.

Note, this library requires c++17. It has been tested with gcc & clang.

Vector2

#include <Vector2.hpp>

To accesses the members you can use either array notation or by member access, with the members x & y.

Vector3

#include <Vector3.hpp>

To accesses the members you can use either array notation or by member access, with the members x, y, & z.

Vector Array

#include <vector_array.hpp>

To access the members you can only use array notation. Also, since this is derived from std::array, you can use >, <, >=, <=, & iterators.

Vector Functions

#include <vector_functions.hpp>

There's not a lot here but I included a few functions I use frequently.

constexpr auto magnitude(const T& vc, F func)

This function takes a vector & a function object as arguments. Currently the functions F must support depend on the size of vc.

If vc is two space, F must have an overload for two scalar values, aka a hypot function.
If vc is three space, F must have an overload for three scalar values, also hypot function.
If vc is any other size, F must have an overload for only one scalar value, this one is just square root.

You can find these in cmath. Unfortunately I cannot find a way around this with c++17.

constexpr std::optional<T> unit_vector(const T& vc, F func)

This function returns a vector of length 1, pointing in the same direction of vc. F is under the same rules as specified in magnitude.

If vc is trivial, this function returns no value.

constexpr auto dot_product(const T& lhs, const T& rhs)
