vec4: nml::vec4& operator+=(const nml::vec4& other)

Add a vec4 to the current vec4.

The sum between two vec4 is calculated this way:

\(\begin{bmatrix} x \\ y \\ z \\ w \end{bmatrix} + \begin{bmatrix} other.x \\ other.y \\ other.z \\ other.w \end{bmatrix} = \begin{bmatrix} x + other.x \\ y + other.y \\ z + other.z \\ w + other.w \end{bmatrix}\)

Example

#include "include/vec4.h"
#include <iostream>

int main() {
        nml::vec4 a(1.0f, 2.0f, 4.0f, 8.0f);
        nml::vec4 b(3.0f, 4.0f, 5.0f, 6.0f);
        a += b;
        std::cout << nml::to_string(a) << std::endl;

        return 0;
}

Result:

[4.000000, 6.000000, 9.000000, 14.000000]
